Dell OptiPlex 466/MXe & PCI probing problems

[Charles Curley <charles h curley lmco com>]

I've installed RH4.2 on Pentiums without any trouble but now I'm trying
to put in on this 486 and I get problems. I place the boot diskette into
the system. At "boot: " hit return and initial loading proceeds until it
starts probing for h/w and gets to the "Probing PCI hardware." (this
machine has no PCI bus) and the system locks up with lots of register
dumping. Here's some of it (... for brevity can provide if necessary):

Probing PCI hardware.
invalid operand: 0000
CPU:    0
EIP:    0010:[<0000004f>]
EFLAGS: 00010002
eax: 00000001   ebx: 00000010   ecx: 00000001 edx: 00000000
...
Process swapper (pid: 0, process nr: 0, stackpage=001c56a4)
...
kfree of non-kmalloced memory: 001c76ec, next= 0000000, order=0
kfree of non-kmalloced memory: 001c76dc, next= 0000000, order=0
kfree of non-kmalloced memory: 001c7bf0, next= 0000000, order=0
idle task may not sleep
idle task may not sleep

Is there a directive I can give to disable the PCI stuff? I checked and
this is the most recent boot image (only one) for RH4.2.
