Been looking for a new retro PC gaming project and, much to my surprise, came across some Socket 478 ISA motherboards. Here is what I found:

Now, as we are all aware 98SE suffers from an issue that prevents it from running well, if at all, on processors faster than 2.1 GHz:

My idea is to try and track down one of these motherboards and, using either a P4 2.0GHz or Pentium 4-M 2.0GHz CPU, try and get one of these working with my current collection of ISA sound cards, a GeForce video card (not sure what to use yet), and do a triple boot DOS 6.22/98se/XP SP2 system. Now, granted, there will be some speed issues that will require MOSLO but the idea really is to use my Slot 1 system for those and use this one for newer titles that do not really require it. That, and really this is just a technical challenge to see just how fast an ISA-based sound card system I can build. 😁

Anyone actually attempt to try this or even have a working system similar to this?

I actually used to dual-boot XP Home and 98SE on a 2.4GHz P4 Prescott box that I had, and it worked great (save for some occasional memory management issues caused by the 1GB of RAM that system had 😁)

ratfink,

Huh. I somehow missed those when I looked earlier but thanks for linking to those!

mr_bigmouth_502,

Interesting. It's really odd that Microsoft reports that there are issues with systems running over 2.1GHz under 98SE but others like yourself seem to do okay barring memory issues.

Were it not for the rather pricey nature of these motherboards I'd be tempted to build two separate ones. Maybe I'll just track down a 512MB PC3200 module which I'm sure I have somewhere and swap between that and the two 1GB modules I have.

Now I just need to decide if I want to splurge a bit and get a 30GB IDE solid-state drive for this one to try it out before I start budging aside money for the motherboard. Granted, it will not really give any major boost in performance but it will run quieter and not run the same risk of drive failure that running an older mechanical one would.

I think the keyword here is installing

Installed and using Win98SE without any issues at all on my 3.06ghz P4 rambus machine but WinXP Pro runs much smoother on it

The trick is to use the unofficial Win98 service pack which adresses alot of issues

i used the unofficial several times the first time it jacked stuff up the second i did in vmplayer cause it wouldn't connect to the update server. does the unofficial service pack go on after official updates? and how do i get JUST the cool addon boot screen that comes with that service pack.

Just an idea but you can also get SocketA boards used with ISA, I know i had an old MSI board with 2 ISA slots and an Athlon XP-M 2800 which used a KT266A chipset and the XP-M's use a 266mhz FSB.

A KT266A chipset based mobo with 2 ISA slots? Are you absolutely sure about that? I searched the net and found a KT266A chipset based mobo roundup review (link below), and they all look about the same: AGP, PCI, and no ISA slots.

Yes I am i pulled it from a compaq PC and flashed with a retail bios. You might have to look for OEM boards but it was a KT266A according to everest. Came with an XP 1700+ from compaq.

Also found this online, it supports Core2 Duo and Core2 Quad and has ISA
