New TYAN Motherboard and Linux 2.1.128

I just upgraded a machine to:
A TYAN S1836DLUAN Thunder 100 ATX, Dual Processor 400MHz,
with an internal SCSI, Adaptec AHA-3940AU/3940AUW.
It was supposed to have an internal Intel 82557 based Ethernet.
I found out it didn't (chips missing). I used a $10 PCI NE2000
compatible clone for now.

I booted Linux 2.1.128 and found that it worked. However, I
found what others have found. Every device was connected to
IRQ10. Although Linux handled the Ethernet and the SCSI on
the same IRQ okay, in DOS (Yes I use that too), the first
packet received by the provided NDIS driver stopped all
hard-disk activity forever.

No amount of mucking with the BIOS Setup would make the
Ethernet board use another IRQ. Then I found, that if I
put the Ethernet board in the LAST (furtherist from the
CPU) slot, it magically used IRQ11. Problem solved.

Another problem was that only two hard disks were visible
from the BIOS via INT 13H. This meant that Lilo would not
work, only print "LI" on the screen and halt. This had to
be solved by mounting the MS-DOS fs, making a /boot directory
on it, copying the contents of /boot to it. Making a sim-link
of /dos/drive_C/boot to /boot, putting vmlinuz in the dos
boot directory, then running LILO. It's all documented in
the Lilo README, but I've heard from others who have had
the same problem.


Cheers,
Dick Johnson
