- I posted here a couple of days ago concerning problems with serial ports
- under Intel SYSVR4.0.3 that I erroneously attributed to IRQ2 from Boca
- ET4000 svga card. Many people offered advice on how to find the trace and
- be sure it was interrupted. I took the board out and discovered that the
- BOCA is one of those boards that lacks the IRQ2 trace. No foil in position
- 4 on the solder side of the card. Back to square one.
-
- Configuration:
- Intel 301Z with 12M of 32 bit memory and 387
- 1.2 M drive A:, 1.44 M drive B:
- Boca ET4000-based SVGA card OR Oak 256K EVGA card(with IRQ2)
- 250M MFM drive, 230M in SYSVR4 partition
- Intel PCL2NIA "smart" ethernet card
- 2 Intel ICC 6 port intelligent serial cards
- Archive 499 QIC-02 controller with 60M Archive tape drive
- All hardware jumpered to the values for IRQ and address that are
- specified in the release notes: 2(9) for enet, 5 for tape, 10 for both
- ICC's.
-
- Software:
- Zenith DOS 3.3+ on bootable DOS partition(formatted as 3.2-style
- partition)
- Intel SYSVR4.0.3, shipped at about the same time that ISC took over
- Intel's UNIX end-user business. Should be nearly identical to early
- ISC SYSR4.0.3(Did they ever make additional changes?), with all
- standard packages installed, plus multiuser. The ICC drivers come from
- an Intel "end-of-life" kit. Marked release 2 for SYSVR4.
-
- Symptom:
- All attempts to access any of the serial ports fail with "unable to
- create"(attempting 'cat /.profile > /dev/tty00{s|h}'), or DEVICE
- UNAVAILABLE or UNABLE TO ACCESS DEVICE(cu -l /dev/tty00{s|h} -s 2400).
- The curly braces indicate optional parameters. These messages vary
- a little from port to port on the ICC's ( ttyi[a-l] or ttyi[A-L] ).
- All of these are while executing as root or as a regular user with
- $HOME/.profile.
-
- I first erroneously associated the failure condition with the possibility
- that there was a conflict between the retrace interrupt found on many VGA
- boards and the fact that the ICC's were on 10. Presumably Intel should be
- able to handle the potential conflicts between the recommended 9 for the
- enet and 10 for the serial cards, all their hardware and drivers. In the
- last stage of the boot process, code for the 186 on the ICC card is normally
- loaded to device /dev/icc. With the Boca card in I get an error message
- about not finding /dev/icc. With the Oak card the "firmware" loads alright,
- but the same errors are encountered in trying to access either the ICC
- serial ports or the COM1-tty00 as before. I ran pkgchk, and got a number of
- errors concerning chksums and permissions, including in the asy pieces. One
- real funny thing is that even though I cannot access tty00, I can install a
- Logitech 3-button C9 serial mouse with mouseadmin and it will work with the
- stock X11R3.
-
- So I removed the ICC package using sysadm, relinked the kernel and
- rebooted. I still cannot access tty00 with cu or cat. I suppose the next
- step is to reload icc and see if that helps. Then reload SYSVR4 and run
- pkgchk. Even loading from tape, however that is a several hour process
- which sometimes hangs when a parity error occurs, making me start over.
-
- Has anyone experienced similar problems (even vaguely similar may help)? I
- read about buggy asy, could that have anything to do with it? Since the
- serial port on the MB is known good with DOS, and the ICC boards work fine
- with Intel SYSVR3.2.2 or Xenix on other boxes, I am pretty sure I am having
- either a software problem or one of those synergistic FUBAR's that DOS
- hardware is so good at.
-
- Any shots in the dark will also be appreciated. Thank you.
