Subject: accessing DOS partitions
Many many months ago I submitted the following bug report to Microport
(on paper):
=========================================================================
doscat(1), doscp(1) do not work with DOS partitions on fixed disk.
System is a Compaq Deskpro 386.
Partition 1 is DOS, partition 2 is System5.
/dev/rdsk/0s6 is linked to /dev/dos/C.
NOTE: This is not 0s5, the "DOS partition".
Approximately the first 2048 bytes of files are successfully displayed
or copied from DOS to UNIX. The rest is missing or consists of garbage.
This happens with both text and binary files, even with proper use of
the "-b" option.
The problem occurs under 1.3.6, and under 1.38.7B.
There is no corresponding problem with DOS floppies.
=========================================================================
I was contacted (by phone) by someone in tech support, who took down
the details. He said that the problem may be with the format of the
FAT on Compaq machines. He promised to look into it and get back to me.
So far, I have heard nothing further on this. Microport never got back
to me. I didn't upgrade to 2.2 because I'm waiting around for the 386
release and wondering, "Did they fix this yet?" Does anyone know?

The file below is used instead of errno.h and provides a textual error
message array like Berkeley. Nothing fancy, but at least I don't have
to look up the errno codes all the time.

I've included some software below that might be useful to Microport
users. It is a backup/restore package that uses cpio and find. An
MS-DOS compatible version of this program will be available shortly.
To extract the program, first uudecode this message, which will
generate dbackup.shr.Z, then uncompress this file and shell the
resulting archive. I'm sending it directly to you because I was
afraid that sending it to microp might have resulted in it being
forwarded to many users who would not really be interested.
[ed: due to size constraints, the program is available from the author]

Subject: Microport system V
I was also interested in how particular Microport's system V is
when running on non-IBM equipment. I thinking of putting together a system
with the primary motivation being running system V. I'd like to know what to
look out for(i.e. any know problems with clone equipment)?

Subject: Bug in 2.2 curses...
I recently came upon a very strange bug in System V/AT 2.2 curses; does anyone
know if it has been fixed? It seems that when keypad mode is on, a getch()
will return a (binary) 0 when the capital P is typed. No other character
appears to be affected and it only occurs when keypad mode is on; everything
works if keypad is off (except, of course, the function keys, which is why
I turned on keypad mode to begin with!).
Has anyone else been bitten by this bug? Also, the F10 key does not seem to
be recognized, although it is sending, as near as I can tell, exactly the
characters I have defined in the "ansi" termdef (a slightly modified version
from that distributed with 2.2, since Microport set all function keys to
sending the same key sequence in the termdef, which they don't using the
distributed /etc/rc.d/keybrd.rc (not that you would want them to!). How
about this one?
By the way, is this mailing list still active? It's been a long time since
I received anything from it (I know, that is kind of like asking "Are you
asleep?).
Thanks.

Subject: File system analyzer
From: umix!rutgers!husc6!panda!genrad!mjy
After noticing that my system performance was degrading somewhat recently,
I realized that I had no means of determining just how badly fragmented my
file systems were. So I wrote a quick-and-dirty utility, fsanalyze, that
scans a file system looking for fragmentation and other inefficiencies.
Below is a sample of its output:
Analyzing file system /dev/dsk/0s2...
File system block size = 1024 bytes
Volume Size = 26778 blocks (27420672 bytes)
336 blocks reserved for super block and inodes
26442 blocks reserved for data
Total inodes = 5344
72.81% inodes used (3891 used, 1453 free)
85.79% data blocks used (22679 used, 3756 free)
468 directories
1259 multiply-linked files
Fragmentation = 21.92%
Indirects = 367 (9.43%)
Double indirects = 4 (0.10%)
Triple indirects = 0 (0.00%)
Oversized directories = 0 (0.00%)
(Note that this file system, which I use for storing USENET news articles,
is small, full, and fragmented!)
I've found it useful, so I thought someone else might too. I'd be glad to
mail the source to anyone who's interested.

From: b-tech!zeeff
Has anyone made the modifications necessary to get ELM 1.7 working under
Microport? Please send diff's if you have.
Also, does anyone know of TCP/IP support for Microport Unix?
