gwr@linus.mitre.org (Gordon W. Ross) (10/24/90)
I received many requests for the BOOTMENU and PFDISK distribution,
so I've mailed the latest version (1.3) to the comp.sources.misc
moderator. The posting (2 parts) should appear there soon.
For those who have just tuned in:
BOOTMENU is a replacement primary boot sector for MS-DOS compatible
machines which allows boot-time selection of the active hard disk
partition using a menu. For example, users with both UNIX and DOS
on their hard disk can choose which system to use at boot time.
PFDISK is a replacement "fdisk" command for
installing BOOTMENU without clobbering your partition table.

My apologies to those who have been patiently waiting for my
BOOTMENU distribution to appear on comp.sources.misc as promised.
I have recently been informed that comp.sources.misc may be
without a moderator and that nothing is getting posted.
I have just mailed the package off to the moderator of the
comp.sources.unix newsgroup. Hopefully, this time it will appear!
Thank you everyone for your patience.
A brief description of the BOOTMENU package is included below
for the benefit of those who missed the earlier announcement.
BOOTMENU is a replacement primary boot sector for MS-DOS compatible
machines which allows boot-time selection of the active hard disk
partition using a menu. For example, users with both UNIX and DOS
on their hard disk can choose which system to use at boot time.
PFDISK is a replacement "fdisk" command for
installing BOOTMENU without clobbering your partition table.
Note that an earlier version of this package has been posted previously,
but described as "boot-hdp." Forgive me for renaming it, but I thought
it would be helpful to use the more descriptive name "bootmenu."

Here is part 1 of the BOOTMENU and PFDISK 1.3 distribution.
BOOTMENU is a replacement primary boot sector for MS-DOS compatible
machines which allows boot-time selection of the active hard disk
partition using a menu. For example, users with both UNIX and DOS
on their hard disk can choose which system to use at boot time.
PFDISK is a replacement "fdisk" command for
installing BOOTMENU without clobbering your partition table.
See the README file at the beginning of the shell archive below for a
general description of this package. Program documentation for both
BOOTMENU and PFDISK are at the beginning of the second posting.

XBOOTMENU is a replacement primary boot sector for MS-DOS compatible
Xmachines which allows boot-time selection of the active hard disk
Xpartition using a menu. For example, users with both UNIX and DOS
Xon their hard disk can choose which system to use at boot time.
X
XBOOTAUTO is similar to BOOTMENU but allows both unattended reboot
Xand the ability to override the automatic selection of the active
Xpartition at boot-time. (I used to call this version boot-hdp).
X
XBOOTMENU cannot do an unattended reboot but is very small and
X(as a result) will not be clobbered if you use the SpeedStor
Xdisk formatting/diagnostics program. (Notes about SpeedStor's
Xusage of the primary boot sector are in the file SStor.txt).
X
XPFDISK is a replacement for both DOS and UNIX fdisk programs.
XThis replacement is distinguished for its ability to put
Xan arbitrary binary image into the primary boot sector without
Xclobbering an existing partition table. PFDISK has no boot
Xprogram built-in, but allows you to take the boot program
Xfrom a file. At least one of the boot program files, such as
XBOOTMENU, must be available to PFDISK if it is expected to
Xinitialize a newly formatted disk. Unlike MSDOS fdisk,
XPFDISK correctly handles partition entries which extend
Xbeyond cyl 1023. Unlike UNIX fdisk, PFDISK is not confused
Xabout the difference between highest-usable-cylinder-number
Xand (beginning-cylinder plus number-of-cylinders).
X
XDocumentation included:
X
XThe file bootmenu.doc explains how to install and use the new
Xboot programs. The file pfdisk.man is manual entry in UNIX *roff
Xformat, and pfdisk.doc is a formatted copy for those without nroff.
X
XHow to compile:
X
XTo build pfdisk, either edit the Makefile to uncomment the
Xappropriate line (i.e. SYS=i386) and type "make", or
Xuse a make command line like:
X make SYS=i386
XThis will just build the pfdisk program and boot sector binaries.
XIt will not try to modify the hard disk boot sector.
X
XThe boot program binaries are distributed as simple HEX encoded
Xtext files. The (included) program hex2bin will convert them
Xfor the benefit of those without the MASM (DOS) assembler.
X
XEnjoy!

X.TH PFDISK 8 "Oct 1990" "Release 1.3"
X.SH NAME
Xpfdisk \- partition fixed disk
X.SH SYNOPSIS
X.B pfdisk
X.I device
X.SH DESCRIPTION
X.LP
X.B pfdisk
Xpartitions the fixed disk identified as
X.I device
Xinto (at most) four parts, each of which may
Xbe independently loaded with an operating system.
XThe actual name of
X.I device
Xdepends on the operating system in use.
XFor ESIX (System V/386) the device name is either
X"/dev/rdsk/0s0" or "/dev/rdsk/1s0".
XFor Minix, it is "/dev/hd0" or "/dev/hd5".
XFor MS-DOS it is a single digit (zero or one).
X.LP
X.B pfdisk
Xreads the hard disk partition table from block zero of
X.I device
Xinto memory and allows the user to examine, modify, or save the
Xpartition table. A regular file may be used instead of a real
X.I device
Xfor testing purposes, though the device geometry must be specified
Xmanually, and some systems will requrire a file-name argument with
Xthe "R" and "W" commands (DOS, ESIX).
X.LP
XThe partition table on
X.I device
Xis NOT modified unless the write command (W) is used with no argument.
X.SH USAGE
X.SS Commands
X.LP
XAll
X.B pfdisk
Xcommands consist of a command word followed by optional
Xblank-separated command arguments.
XNote that only the first letter of a command word is significant
X(except for "wq" and "q!").
XAll command letters are accepted in either upper or lower case.
XNumeric arguments are specified using C syntax.
XExtra arguments are silently ignored.
X.LP
XThe commands are:
X.TP
X.B ?
XPrints a command summary (help).
X.TP
X.BI 1 " sys_id first last sys_name"
XSet the partition table entry for part one, using:
X.I sys_id
Xas its system ID code,
X.I first
Xas the lowest numbered cylinder it uses,
X.I last
Xas the highest numbered cylinder it uses, and
X.I sys_name
X(optional) as the system name (in the menu name table).
X.TP
X.BI 2|3|4 " sys-id first last sys-name"
XSimilar to
X.B 1
Xbut sets partition two, three, or four, respectively.
X.TP
X.BI A " number"
XMark partition
X.I number
Xas active (so it will be used for booting). If
X.I number
Xis zero, no partition will be active.
X.TP
X.BI G " cylinders heads sectors"
XInform
X.B pfdisk
Xwhat the geometry of the device is.
X.TP
X.B I
XPrint a summary of the known ID codes.
X.TP
X.B L
XList the partition table.
XSee
X.B "Output Format"
Xbelow.
X.TP
X.B Q
XQuit without saving. If the memory copy of the partition table was
Xmodified, a warning will be issued and the command ignored.
X.TP
X.B Q!
XQuit, even if the memory copy of the partition table was not saved.
X.TP
X.BI R " file-name"
XRead boot sector from
X.I file-name
X(if given) otherwise read from
X.I device.
X.TP
X.BI W " file-name"
XWrite boot sector to
X.I file-name.
X(if given) otherwise write to
X.I device.
X.TP
X.B WQ
XSame as "write" followed by "quit".
X.TP
X.B #
XThis line is a comment (to be ignored).
X.SS "Output Format"
X.LP
XHere is a sample of the output from the
X.B L
Xcommand:
X.LP
X.nf
X# Partition table on device: /dev/rdsk/0s0
Xgeometry 1222 15 34 (cyls heads sectors)
X# ID First(cyl) Last(cyl) Name # start, length (sectors)
X1 4 0 127 MS-LOSS # 34, 65246
X2 129 128 255 Minix # 65280, 65280
X3 0 0 0 # 0, 0
X4 99 256 1220 ESIX # 130560, 492150
X# note: last(4): phys=(1023,14,34) logical=(1220,14,34)
Xactive: 4
X.fi
X.LP
XThis output format is carefully constructed so that it
Xmay be saved in a file (by redirecting standard output)
Xand later used as input (by redirecting standard input).
XOn a UNIX system, one can save this output using the command:
X.IP
X(echo L) | pfdisk device-name >
X.I save-file
X.LP The printable representation saved in
X.I save-file
Xis a complete record of the partition table.
XOn a UNIX system, one could use
X.I save-file
Xto re-initialize the partition table using the command:
X.IP
X(cat save-file ; echo wq) | pfdisk device-name
X.LP
XConsistency of each partition table entry is checked
Xwhile the table is listed. Any inconsistencies discovered
Xare reported in a commentary note as shown above.
X.SS "Physical vs. Logical"
X.LP
XEach partition table entry has both "physical" and a "logical" fields.
XThe physical fields specify the lowest and highest cylinder,head,sector
Xcombinations to be used in that partition. The logical start field
Xhas the total number of sectors which precede this partition, and
Xthe logical length field has the total number of sectors contained
Xin this partition. These fields should be self consistent unless
Xthe disk has more than 1024 cylinders.
X.LP
XThe physical cylinder fields are only ten-bits wide so the contents
Xare limited to 1023. The logical sector fields are 32 bits wide and
Xalways show the true logical beginning and length of the partition.
XGenerally, the physical start field is used only to locate the
Xsecondary boot sector, and the logical start and length fields are
Xused to actually delimit the partition used by a particular system.
X.SS "Partition Names"
X.LP
XThe
X.B Name
Xfield in the partition table is treated specially if the
X.B bootmenu
Xprogram is installed in the primary boot sector.
X(See the file bootmenu.doc for more information.)
X.B pfdisk
Xcan recognize the name table used by
X.B bootmenu
Xand will show the actual names present in that name table.
XIf any other boot program is used then the
X.B Name
Xfield reflects the result of a table-lookup of the system ID.
X.LP
XIf you provide a name when setting any partition entry, the
Xboot-sector is marked as using a name table, so that on
Xsubsequent uses of
X.B pfdisk
Xyou will see the partition names you have specified.
X.SS "Boot program replacement"
X.LP
XYou can replace the boot program in your boot sector without
Xaffecting the partition table by using
X.B pfdisk
Xas follows. First, (as always) save a copy of the current boot
Xsector (on a floppy) using the "W file" command. Then, use the
X"R file" command to read the new boot program.
XIf the boot program read in is less than 446 bytes long, the
Xpartition table will be unchanged.
X.LP
XUnlike the DOS or UNIX
X.B fdisk
Xprograms,
X.B pfdisk
Xhas
X.I NO
Xboot program compiled into its executable image.
XIf you wish to use
X.B pfdisk
Xto partition a newly formatted hard disk, you must have a boot program
Ximage available to read in using the "r file" command.
XTwo boot programs, "bootmenu.bin" and "bootauto.bin" are distributed with
X.B pfdisk
Xand should be found with its source files. See the file bootmenu.doc
Xfor further information about these boot programs.

X BOOTMENU -- a BOOT sector program with a MENU
X ---------------------------------------------
X by Gordon W. Ross, Aug 1990
X
X This program is loaded by the PC ROM BIOS and is responsible
X for selecting one of four partitions to boot from. The normal
X (MS-DOS) version of this program always boots the "active"
X partition, but this version allows any partition to be
X selected for booting, wether marked "active" or not.
X
X Two versions of this program are now distributed:
X
X BOOTMENU is small (less than 256 bytes of code) and compatible
X with the SpeedStor hard disk formatting package. (Note that
X SpeedStor writes in several locations in the boot sector!)
X This version, however, does not allow unattended reboots.
X After BOOTMENU displays its partition menu, it waits
X indefinitely for someone to select a boot partition.
X
X BOOTAUTO (previously called "boot-hdp") is a full-featured
X boot program which allows boot-time partition selection, but
X also provides a default selection which is used if no user
X input arrives within five seconds.
X
X The behaviour of BOOTAUTO is as follows:
X
X BOOTAUTO displays the message:
X Booting device: hd0,
X and then pauses for a five second delay.
X
X If the user presses any key before the delay expires, a menu
X of bootable partitions is displayed, and the user is prompted
X for the number of the partition to boot from. If no key is
X pressed before the delay ends, the first partition marked as
X "active" is used. If no partition is marked as active, the
X boot menu is presented without delay, as if a key were struck.
X In essence, this program interprets the "active" mark (if
X present) as a default choice indicator.
X
X Once a partition has been selected this program displays the
X selected partition number and loads its secondary boot
X program. Errors are printed if (1) the selected partition is
X empty, (2) the secondary boot program lacks a valid signature,
X or (3) an error occurs while reading the secondary boot sector.
X
X Installation:
X ------------
X The "pfdisk" utility included with this program simplifies
X installation of BOOTAUTO into the primary boot sector.
X Instructions for using "pfdisk" are in the pfdisk.doc file.
X
X Limitations:
X -----------
X Names in the boot menu:
X
X BOOTMENU and BOOTAUTO contain a name table that is used to
X generate the boot menu. This name table is recognized (using
X a signature) and updated by pfdisk but not by other fdisk
X programs. If another fdisk program is used to modify the
X partition table, the name table may be left with misleading
X entries. Note that pfdisk only updates the name field for any
X entry when the entry is set using the optional name field, i.e:
X
X pfdisk> 1 4 0 127 MS-LOSS
X
X Furthermore, the name supplied as the fourth arg. is truncated
X to eight characters. (Space is tight in the boot sector.)
X
X The signature which flags the presence of a name table is
X written into any boot sector every time the name argument is
X given in a partition setting command (1,2,3,4). This
X signature occupies locations 0x1A0 -- 0x1AD which does not
X clobber anything used by any of: UNIX or DOS boot programs,
X SpeedStor or WesternDigital Auto-configuring controllers.
X
X Booting inactive partitions:
X
X MS-DOS will boot from an inactive partition without needing
X any modifications. Unfortunately, some systems refuse to boot
X from a partition which is not marked as active.
X
X ESIX (from Everex Systems) Sys.V Rel.3.2 will not (as shipped)
X boot unless its partition is marked active. Other versions of
X Sys.V/386 are similar in this regard. The easiest solution is
X to mark the UNIX partition as active, and use BOOTMENU to
X offer you a choice between DOS and UNIX.
X
X If you wish, it is also possible to patch UNIX so that it will
X boot without demanding that its partition be marked active.
X These patches (called "esix-boot") are available from the
X author. Send EMAIL to gwr@world.std.com if you want them.

XNAME
X pfdisk - partition fixed disk
X
XSYNOPSIS
X pfdisk device
X
XDESCRIPTION
X pfdisk partitions the fixed disk identified as device into (at
X most) four parts, each of which may be independently loaded with
X an operating system. The actual name of device depends on the
X operating system in use. For ESIX (System V/386) the device
X name is either "/dev/rdsk/0s0" or "/dev/rdsk/1s0". For Minix,
X it is "/dev/hd0" or "/dev/hd5". For MS-DOS it is a single digit
X (zero or one).
X
X pfdisk reads the hard disk partition table from block zero of
X device into memory and allows the user to examine, modify, or
X save the partition table. A regular file may be used instead of
X a real device for testing purposes, though the device geometry
X must be specified manually, and some systems will requrire a
X file-name argument with the "R" and "W" commands (DOS, ESIX).
X
X The partition table on device is NOT modified unless the write
X command (W) is used with no argument.
X
XUSAGE
X Commands
X All pfdisk commands consist of a command word followed by
X optional blank-separated command arguments. Note that only the
X first letter of a command word is significant (except for "wq"
X and "q!"). All command letters are accepted in either upper or
X lower case. Numeric arguments are specified using C syntax.
X Extra arguments are silently ignored.
X
X The commands are:
X
X ? Prints a command summary (help).
X
X 1 sys_id first last sys_name
X Set the partition table entry for part one, using:
X sys_id as its system ID code, first as the lowest num-
X bered cylinder it uses, last as the highest numbered
X cylinder it uses, and sys_name (optional) as the system
X name (in the menu name table).
X
X 2|3|4 sys-id first last sys-name
X Similar to 1 but sets partition two, three, or four,
X respectively.

X (echo L) | pfdisk device-name > save-file
X
X save-file is a complete record of the partition table. On a
X UNIX system, one could use save-file to re-initialize the parti-
X tion table using the command:
X
X (cat save-file ; echo wq) | pfdisk device-name
X
X Consistency of each partition table entry is checked while the
X table is listed. Any inconsistencies discovered are reported in
X a commentary note as shown above.
X
X Physical vs. Logical
X Each partition table entry has both "physical" and a "logical"
X fields. The physical fields specify the lowest and highest
X cylinder,head,sector combinations to be used in that partition.
X The logical start field has the total number of sectors which
X precede this partition, and the logical length field has the
X total number of sectors contained in this partition. These
X fields should be self consistent unless the disk has more than
X 1024 cylinders.
X
X The physical cylinder fields are only ten-bits wide so the con-
X tents are limited to 1023. The logical sector fields are 32 bits
X wide and always show the true logical beginning and length of
X the partition. Generally, the physical start field is used only
X to locate the secondary boot sector, and the logical start and
X length fields are used to actually delimit the partition used by
X a particular system.
X
X Partition Names
X The Name field in the partition table is treated specially if
X the bootmenu program is installed in the primary boot sector.
X (See the file bootmenu.doc for more information.) pfdisk can
X recognize the name table used by bootmenu and will show the
X actual names present in that name table. If any other boot pro-
X gram is used then the Name field reflects the result of a
X table-lookup of the system ID.
X
X If you provide a name when setting any partition entry, the
X boot-sector is marked as using a name table, so that on subse-
X quent uses of pfdisk you will see the partition names you have
X specified.
X
X Boot program replacement
X You can replace the boot program in your boot sector without
X affecting the partition table by using pfdisk as follows.
X First, (as always) save a copy of the current boot sector (on a

X mand to read the new boot program. If the boot program read in
X is less than 446 bytes long, the partition table will be
X unchanged.
X
X Unlike the DOS or UNIX fdisk programs, pfdisk has NO boot pro-
X gram compiled into its executable image. If you wish to use
X pfdisk to partition a newly formatted hard disk, you must have a
X boot program image available to read in using the "r file" com-
X mand. Two boot programs, "bootmenu.bin" and "bootauto.bin" are
X distributed with pfdisk and should be found with its source
X files. See the file bootmenu.doc for further information about
X these boot programs.

XNote: SpeedStor (sstor) modifies SEVERAL locations in the boot sector!
X
XThe SpeedStor manual says it does not modify locations 0xEA -- 0x17D
XBUT THEY LIE! If you use the "Parameter Override" feature, "sstor"
X(evidently) puts the new disk parameters in locations 0xEA -- 0xF9.
X
XIf you install BOOTAUTO and then run sstor, using the parameter
Xoverride feature, you will have clobbered the BOOTAUTO program in a
Xway such that it hangs or repeats its menu when you make a selection!
X(Yes, I learned this the hard way...)
X
XTo get around this problem, I wrote a slimmed-down version of the boot
Xprogram, called BOOTMENU, which has unused "holes" strategicly placed
Xin the locations known to be clobbered by SpeedStor. Though this
Xversion has the advantage of SpeedStor compatibility, it does not have
Xthe ability to do automatic, unattended reboots like BOOTAUTO can.
X
XFor future reference, also note that sstor will modify locations
X0x17E -- 0x1BD if you create SpeedStor partitions. To their credit,
Xthis is indeed mentioned in the manual.

X; bootmenu: BOOT Hard Disk Partition
X; by Gordon W. Ross, Aug 1990
X;
X; See the file bootmenu.doc for user instructions.
X;
X; This version of bootmenu is compatible with SpeedStor.
X; See the file sstor-bug.txt for the gory details.
X;
X; The following is an outline of the program:
X;
X; Relocate self from 0x7c00 to 0x0600
X; Display partition menu
X; Prompt for and read user selection
X;
X; Boot from the selected partition:
X; (was selected by user, or was active)
X; Read first sector of selected partition into 0x7c00
X; Verify good second-stage boot sector (magic word)
X; Set-up correct register values and jump to it.
X;
X
XCODEORG equ 0600h ; offset of this code in code seg
X; All values computed from offsets in codeseg need to be
X; adjusted by adding CODEORG to each. The obvious method,
X; using "org CODEORG" causes MASM/LINK to fill in the space.

Bootmenu *was* posted to comp.sources.misc as Brandon was clearing the queues just prior to passing off the responsibilities. The indexes for the group are incorrect in not showing bootmenu as being posted. David is correct in pointing out that bootmenu is archived on uunet as well as other c.s.misc archives. Below is the posting information that has been added to the group's indexes. v15i084 bootmenu/part01 BOOTMENU and PFDISK 1.3 (part 1/2) v15i085 bootmenu/part02 BOOTMENU and PFDISK 1.3 (part 2/2) -Kent+ -- Kent Landfield INTERNET: kent@sparky.IMD.Sterling.COM Sterling Software, IMD UUCP: uunet!sparky!kent Phone: (402) 291-8300 FAX: (402) 291-4362 Please send comp.sources.misc-related mail to kent@uunet.uu.net.

When I power up my system, I get a nice little menu which allows me to press "3" to boot dos3.3 or "4" to boot esix. People who are tired of the hassles of switching between dos and unix should look at bootmenu. Patrick Wolfe Internet: patrick@whistle.kai.com UUCP: uunet!kailand!whistle!patrick

Where'd Kent go? I am right here... I don't usually read this group so I was a little slow to respond... :-) As I have stated previously, Brandon posted bootmenu in December. I am still posting as fast as I get things. I would not describe 179 postings in 79 days as "nothing is getting posted"... :-) Is this an old message we are discussing ??? If not you had better question who informed you as to the age of their information. 90+ days in this case... :-) -Kent+ -- Kent Landfield INTERNET: kent@sparky.IMD.Sterling.COM Sterling Software, IMD UUCP: uunet!sparky!kent Phone: (402) 291-8300 FAX: (402) 291-4362 Please send comp.sources.misc-related mail to kent@uunet.uu.net.
