Yep. It's in the FIC FAQ:

Isn't that pretty much academic, since you can't physically use both of
these slots at once?

I doubt you'll get rich selling off components of this vintage. What's
the intended use for this machine? How many cards would you need to
cram into the case? What OS do you envision using?
I'm reading this group because I'm in the final stages of upgrading my
wife's 503+-based machine (1.15JK35 BIOS, PCB rev. 1.1A, K6-2/450, AT
PSU) from W98SE to Windows 2000 SP4. If you want to know how I got it
working, read on! Hardware: ATI Rage AGP-2X video, Creative SB PCI64
sound, Netgear FA311 10/100 ethernet, ACARD AEC6880 ATA-133/RAID
controller with mirrored IBM Deskstars as boot device. No ISA cards.
It was a struggle getting all three PCI cards to function in Win2K with
the AGP video adapter present--the slot order I used for Win98 did not
work at all, and in fact FIC's FAQ advises leaving PCI #1 empty.
Several times I would get the network card "installed" but couldn't ping
anything; and adding the third PCI card usually meant a hang just after
the logon screen.
I almost gave up in frustration, but I put in a few more hours of
methodical attempts, wrote down everything I did, and finally got it.
It's no 3GHz screamer, and it could use some more RAM, but all in all
it's a pretty snappy machine and entirely adequate for word processing,
e-mail, internet etc. I'm certainly not sorry I stuck with it, and I'm
sure my wife will be thrilled if I ever stop tweaking it and let her use
it ;-)
I have no idea if my solution is generalizable, but here's the synopsis
I was planning to post; I might as well do it here as anywhere:
--Swapped the two PCI cards nearest the AGP slot. I arrived at this
much later after trying all sorts of permutations. The key was getting
the same IRQ assignments that worked in Win98--which is hard to do
because you can't just turn off automatic config and manually set them
in Win2K/XP. I don't know whether the relative slot order or the
characteristics of the individual cards are the critical thing
here...but I got good results with the RAID controller in slot #1 (IRQ
10, soundcard in #2 (IRQ 11), NIC in #3 (IRQ 5). I had #1 and #2
reversed in Win98; the controller was a Diamond FirePort SCSI.
--In BIOS: Set PnP OS to "No", kept the auto-assigned IRQs (you might
have to go with manual if you have legacy ISA cards). I stuck with the
10,11,5... ordering, which is what worked in W98. Turned off all power
mgmt stuff. Disabled 'assign IRQ for VGA'. Disabled serial port #2,
parallel port and USB, all of which seemed to be preferentially grabbing
IRQs I thought I needed.
--Installed Win2K (or XP) with the Standard PC HAL by hitting F7 (or F5)
at first setup bluescreen when it asked for mass storage drivers. F7 is
silent; F5 brings up a menu. (You can also then hit F6 if you have a
RAID/SCSI/ATA133 controller to install).
--Turned off IRQ Steering in Dev Mgr -> Computer -> Properties. What
the BIOS assigns, stays. (I did this early, and now that everything
works I'm too chicken to turn it back on to find out if this step is
really necessary.)
--I had USB disabled in the BIOS; when I turned it back on it took IRQ 7
but showed up as "unsupported VIA USB host controller". I read mixed
reports on getting USB functionality from this board--many reports of
instability. I went for "update driver", "show all compatible drivers",
and chose "VIA Standard USB host controller". It installed the usb root
hub device, and my Olympus digital cam works now, at least. No
noticeable instability problems thus far!
Sorry to hijack the thread--but I hope this detailed account helps
someone get a W2K or XP upgrade going on the 503+.
