I have recently acquired Minix 1.3 and am interested in putting
it on my hard disk and then upgrading to 1.5.10. I have down-
loaded the Shoelace package to help me put Minix on the hard disk,
but I have a few problems that are preventing me from doing it.
My system configuration is: 6 Mhz AT w/ HD floppy, 21 Meg hard
disk (C:), 31 Meg hard disk (partitioned into 14 Meg D: and 17
Meg E:). The C: drive has all MS-DOS software on it. I would
like to install MINIX on the D: and E: partitions and then use
Shoelace to selectively boot either operating system.
In my understanding, /dev/hd0 refers to the nonpartitioned C:
drive, /dev/hd1 refers to the D: drive and /dev/hd2 refers to
the E: drive. Is this correct?? I tried to "mkfs /dev/hd2
<size>" and then "mount /dev/hd2 /usr/tmp". mkfs worked, but
when I tried to mount, it said "not a filesystem" (or something
like that). I need the hard disk partition so I can copy the
Shoelace files somewhere before I compile them.
Does anyone have any hints on the best way to set up a hard
disk system for co-existence of MS-DOS and MINIX or any info
on the best way to install Shoelace? Any help would be
greatly appreciated.

It appears to me from your description that you have *two* hard disk drives. The 21Mb drive is known to MessyDog as C:, and the 31Mb drive is known to MessyDog as D: and E: (two partitions). >In my understanding, /dev/hd0 refers to the nonpartitioned C: >drive, /dev/hd1 refers to the D: drive and /dev/hd2 refers to >the E: drive. Is this correct?? No. /dev/hd0 refers to *all* of drive 0. /dev/hd[1234] refers to partitions 1-4 of drive 0. /dev/hd5 refers to *all* of drive 1. /dev/hd[6-9] refers to partitions 1-4 of drive 1. > I tried to "mkfs /dev/hd2 ><size>" and then "mount /dev/hd2 /usr/tmp". mkfs worked, but >when I tried to mount, it said "not a filesystem" (or something >like that). I need the hard disk partition so I can copy the >Shoelace files somewhere before I compile them. It's strange that mkfs should `work'. Drive 0 only has one partition (known as MessyDog drive C:). Writing to it should fail. Failure to mount is consistent with the fact that /dev/hd2 doesn't exist. What you should have tried was /dev/hd6 and /dev/hd7 (for MessyDog drives D: and E: respectively). Whatever you do, don't use /dev/hd0 or /dev/hd1. You have been warned. If I were you I would either rename these to /dev/HD0 and /dev/HD1 to avoid slips when typing. >Does anyone have any hints on the best way to set up a hard >disk system for co-existence of MS-DOS and MINIX or any info >on the best way to install Shoelace? Any help would be >greatly appreciated. Your other problem will be that the BIOS will boot from hard disk drive 0 in preference to drive 1. This means that the MessyDog C: drive will boot. You can install winiboot there, but winiboot will not boot partitions across disk drives --- it will only allow you to boot partitions on the *current* drive. Thus in order to allow you to select the system at boot time, you will have to build a small Minix partition on drive 0. You can make it small then use /etc/mount to mount the /usr partition on drive 1.
