PCI problem

by JR » Fri, 17 Aug 2001 10:08:08

Having a problem installing RH7.1 on an old box. I have searched a number
of archives and seen similiar problems posted, but haven't seen a solution.

Computer: No name clone, P90, Biostar MB, AMIBIOS circa 1995, 32MB, 2G IDE,
PCI NIC(tulip clone)

Install hangs at PCI probe. Used pci=conf2 to complete installation.

On boot:
pci=conf1 - clears screen at PCI probe but does come up, just no display
(interesting but not too useful)

pci=conf2 - comes up fine, but doesn't probe PCI bus. (Interesting that
video card is PCI). Obviously, doesn't find NIC.

Manual load (/sbin/modprobe tulip) fails with: "init_module: No such
device".

Any help would be appreciated.

1. Thinkpad 760, PCI problem, serial port problem

All:

I'm running Slackware kernel version 2.0.29 and pcmcia 2.9.2 on the
ThinkPad 760, and everything seems to pretty much work. However I have
two problems which may be related (1 & 2 below), and a third, lesser
problem.

1. PCI

I get the following warning at boot time:

Console: 16 point font, 400 scans
Console: colour VGA+ 80x25, 1 virtual console (max 63)
pcibios_init : BIOS32 Service Directory structure at 0x000fda50
pcibios_init : BIOS32 Service Directory entry at 0xfda60
pcibios_init : PCI BIOS revision 2.10 entry at 0xfdaa0
Probing PCI hardware.
Warning : Unknown PCI device (8086:1235). Please read include/linux/pci.h
Warning : Unknown PCI device (104c:ac12). Please read include/linux/pci.h
Warning : Unknown PCI device (104c:ac12). Please read include/linux/pci.h

2. Serial port.

I cannot get the standard 9-pin serial port to talk to my printer. I
ran setserial as

setserial /dev/cua0 auto_irq autoconfig

and setserial -b shows

/dev/cua0 at 0x03f8 (irq = 4) is a 16550A

which looks right. Howver,

cat foo>/dev/ttyS0 sends nothing to the printer.

Third problem:
3. iBCS.o

When I ran kernel 2.0.27 this module (which was in /lib/modules/misc)
loaded ok. However, when I built 2.0.29, a new version of iBCS.o did
not get built, and so the kernel complains about mis-matched symbols
at boot time.

Any & all help would be greatly appreciated.

Thanks,
