- I'm *very* pleased to get the newest 386bsd; it looks like some
- really nice work.
-
- I just thought I would report some problems I'm seeing and some
- possible areas to examine?)
-
-
- First of all, I'd like to report that the cursor seems to be confused
- for monochrome cards. The line appears above the space instead of
- below it. I got around this by using a CGA card displaying on my
- monochrome monitor (a clever little card from an old Tandy 1200H
- machine.)
-
- Next, with respect to silo overflows in the serial driver.
- I was *plagued* with them when I was using an MFM disk, replacing
- that with an IDE disk appears to have corrected the problem. Could
- there be a problem with interrupts being left too high, too long in the
- wd driver?
-
- Next, I noticed that when running screen (the binary supplied in the
- etc01 distribution) on a serial line, the characters get buffered
- an extra time, some how, some where. This isn't the case for screen
- running on the console; so there could be a problem in the serial driver
- (i.e. probably not the pty driver.)
-
- Next, I thought I would try and replace the com driver with the latest
- one I had for 0.0 (in which Chris cgd@agate.berkeley.edu had implement
- bidirectional lines); however, the first compile of the locked up (it was
- over a serial line.) I could type *nothing* anywhere and get any
- response - even ctrl-alt-delete; so I powered down and rebooted.
-
- After the fsck's; I restarted the compile on the console instead of over
- a serial line. This time, compiling part of ../../vm, the machine
- spontaneously rebooted.
-
- The third time was the charmer, and I got everything compiled...
-
- So, now, after complaining so much :-), let me offer one trivial
- helpful hint. To compile trek (in the etc01 distribution) you need
- to remove the -lcompat from the Makefile line (there is no compat library
- for 386bsd), and properly define gtty() in main.c. I added the following
- two lines just before main():
-
- #define gtty(fd, argp) ioctl(fd, TIOCGETP, argp)
- #define stty(fd, argp) ioctl(fd, TIOCSETP, argp)
-
-
- Finally, let me give anyone concerned my configuration details:
-
- Hardware: DTK KEEN2000 (20mhz 386), with IIT FPU, with ROMs dating
- from 1988.
- Video: CGA adapter (displaying on monochrome)
- Disk: Connor Peripheral 240AT (IDE)
-
- I re-installed everything myself (going by Chris's instructions,
- thanks Chris) to provide a large swap space and separate / and /usr
- partitions, my disklabel looks like (in case is an obvious problem
- with my swap partition):
-
- type: ESDI
- disk: qp240at
- label:
- flags:
- bytes/sector: 512
- sectors/track: 36
- tracks/cylinder: 16
- sectors/cylinder: 576
- cylinders: 832
- rpm: 3600
- interleave: 1
- trackskew: 0
- cylinderskew: 0
- headswitch: 0 # milliseconds
- track-to-track seek: 0 # milliseconds
- drivedata: 0
-
- 8 partitions:
- # size offset fstype [fsize bsize cpg]
- a: 81792 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 141)
- b: 36864 81792 swap # (Cyl. 142 - 205)
- c: 479232 0 unused 0 0 # (Cyl. 0 - 831)
- h: 359424 118656 4.2BSD 1024 8192 16 # (Cyl. 206 - 829)

- p.s. If anyone would like it, I have disktab entries for a CP240AT (as above)
- and a Micropolis 1325/1335.
