What's the deal with ATI cards and PCI lock-ups?

[Bruce Morgen]

I've inherited a few ATI PCI
video cards -- most notably
a like-new All-In-Wonder 128
-- and they seem to have a
PCI bus conflict with my
Tekram DC-390U2W SCSI
controller. The cards sign
on briefly before the HP
Vectra boot-up bar appears
and the boot continues long
enough for the system BIOS
to sign on, but at the point
where the Tekram card's BIOS
normally signs on the screen
goes blank and the system
locks up solid. The same
system boots up normally to
Win2K with several non-ATI
cards, including a Voodoo3
and an old Creative Labs
Graphics Blaster (Cirrus
Logic Laguna 5464). The
only one of the ATI cards
that works normally in this
system in an ancient is an
ancient Mach64 (early Rage
w/2MB VRAM). What gives?

The system is a two-CPU
HP Vectra XW 6/200 PC
workstation upgraded with a
pair of Pentium II 333
Overdrives and the latest
flash BIOS update from HP.

Any and all thoughts are
much appreciated -- I've
contacted ATI but I thought
it might be a good idea to
ask the ATI user community
too. Thanks in advance!

hi... i assume that you have made sure that the IRQ settings aren't the
same for both?

It's hard to check when
the system won't boot,
but I took care to put
the cards into widely
separated PCI slots. I
was able to boot up to
Win2K with a non-ATI
card AND the All-In-
Wonder 128, getting my
video from the non-ATI
card -- I then was able
intall the ATI drivers
from the CD-ROM and get
the All-In-Wonder
listed in Device
Manager. However, when
I removed the non-ATI
card the system
reverted to the same
unbootable condition.

This is similar to the
way my son's old Compaq
Presario, where the
boot-up process (POST,
etc.) was displayed by
the motherboard video
and he was able to get
his Radeon to display
when Win2K's GUI came
up -- except this HP
box doesn't have a PCI
slot to spare for a
second video card to
enable that kind of
kludge.

Grrr -- frustrating!
Thanks for trying to
help, I appreciate it.
