Interesting Question: Are there any AT (yes AT) motherboards that supports Pentium III 700 mhz (100 Mhz FSB)

[LiLxJohnny]

Are there any AT (yes AT) motherboards that supports Pentium III 700 mhz (100 Mhz FSB)?

I'm asking b/c I have this fileserver case that I would like to utilize but the fileserver case accepts only AT motherboards. It wasn't designed to allow different backplates to be used. Ideally, an AT motherboard what has AT/ATX power connectors so I can still use ATX power supplies.

Any input would be useful.

Doubtful. Even if there was, it would be a specialty part and probably more expensive than a new ATX case. Sorry.

Actually, I found a few motherboards already with BIOS support for the CPU that I mentioned .. my only problem now is trying to find them ..

For those that may even be interested, here's the list I found:
1. Gigabyte GA-6BA rev3.0 or greater. Link Here
2. Tyan Tsunami S1830 Link Here
3. Asus P2B-B

If there isn't a backplate for ATX, take a Dremel to it.

I did this with a Supermicro case, nice thick steel, but only took my 30 mins to get though it, and was still using that old AT case with my Tbird and Abit KT7 (until I upgraded last year)

I'm hoping that to be my last option b/c I do know that these motherboards are still out there ... are there any others that I failed to mention?

Here you go. Another

I installed a baby EPOX dual AT/ATX power in my wife's system. I had to use the dremmel because I wanted to replace the PS with an ATX one, but otherwise it would have dropped in just fine. It is running a 1.1 pentium. I think it is a EP-3VWB+. I got it at newegg a year or so ago.

Because I replaced the AT PS with an ATX, I also had to replace the power switch. Frys carries them.

I have an abandoned bastard of a motherboard, a PC Chips M729MRT Bxcel board, which can support an AT or an ATX power supply. It can also support both an S370 cpu (up to 533) and a Slot 1 (currently a C566@850). I had it apart today to put a newer video card in it in fact. PCChips has never been known for ANY performance (other than poor) but this board is rock stable and serves me well as a third PC tucked away in the basement.

Hey, I've actually worked on one of those like 6 months ago. Very strange setup for sure. Too bad it fried or I might have still had it around ( built him a new system).

Gigabyte had the GA-6VA7+ and Soltek had the SL-63AV+, both were virtually identical in features.

- Baby AT
- VIA Apollo Pro
- S370 PIII/Celeron 'Coppermine' Support up ~1GHz
- PC100/133 SDRAM

I've used a few of the Soltek boards for AT upgrades. I had the Gigabyte boards on backorder for two weeks but nobody could tell me when they would be in again so I canceled and ordered the Solteks. My sister is currently using one with a 733PIII but the primary IDE channel is dead.

The problem is not whether these boards were ever available but if you can still find any.

Exactly what I just picked up from here in the AT forums .. thanks for all your inputs on this.

Johnny, if you have any problems running this board, lemme know ! If you use W2K with it, there's an issue with the IDE controllers not running in UDMA mode. I can send you the links and forum disscussion on solving this. GL
