ATX was scary newness at the time and there were things like this. Just as there are baby AT Super 7 boards.

Pentium II was very expensive though so I think it's less often you run into this sort of upgrader's board for them.

That's a PCChips board... they did a lot of weird stuff like that. I can't say I've ever seen that particular one though.

Should make an alright Win9x box. You've got an AGP slot (that probably even works properly, being that it's an Intel chipset), and it's a pretty good layout for whatever long cards you may want to install. The onboard sound should theoretically be pretty decent for DOS games too, being a re-badged CMI8330... you'd just need to find one of the little breakout thingies to plug into the header. (Which shouldn't be too difficult, since it's the same as the one used on most other PCChips boards in the late '90s.)

Unfortunately you're stuck with 66mhz bus speed, although, it might have options for 75 and/or 83mhz. I wonder if the BIOS would allow for a Coppermine Celeron... probably not, but it'd be something to play with if you happen to have a slotket laying around.

And just a side note, technically all 440LX boards should support EDO, it's just that they usually require EDO DIMMs (the quite rare 3.3V unbuffered variety).

I've also seen a Socket 370 AT board. It didn't have SIMM slots though, only DIMM.

Hi guys did not post here in ages :p

Found this while dumpster diving

i also found this while dumpster diving 😁 🤣

You got everything you need here:
http://www.elhvb.com/mobokive/archive/PcChips … M719/index.html
it's a PCChips M715 mobo

PS:If you want to flash it please ask me as i have the same mobo and flashed its bios successfully

Edit:#100 Post!

Haha! Thanks for the info guys!

Thank you much for the links Sebaz. I do not know if this board works fine yet but it looks very clean and i find it funny so i will keep it.

I have decided on the short term destiny of this board, Im gonna try to move it to an ATX case, should be doable as it can also use an ATX psu and I located the pwr_on header on the board.

The idea is a really want to use this nice AT case for some homeless 486 board i have laying around 😁

BX-chipset ! 😲

I remember I have some Jetway(?) BX AT motherboard laying around somewhere. Dunno if it works though, not even sure it has the BX chipset or some VIA chipset, been a while since I last had a look at it.

Iirc there was even a P4 AT motherboard made.

I have one of those PCChips M715 boards, too. Got it as spare part for my Soltek SL-61C (another Intel 440EX-based AT board), which I use as my secondary Win9x machine. I built it mainly for Glide gaming: Voodoo^2 SLI, Mendocino Celeron 500 and only 256 MB of RAM, due to an imposed limitation in 440EX chipset's maximum memory size (440LX, being almost the same chipset, supports up to 512 MB of SDRAM or 1 GB of EDO RAM). Can't remember whether I tried a Coppermine Celeron. Not only you will need a Celeron II compatible slocket, you will also have to take care with CPU voltage issues: 2.0V for Mendocino core, 1.5-1.65V for Coppermine-128 core.

Then if you want to use an ATX psu i highly recommend you to update the BIOS because acpi support on stock/default bios is bad

I have a PCChips board that houses a Slot 1 and a Socket 370, can't use them both at the same time though. Horrible board, makes a Celeron 400 perform like a Pentium 200. 😜

Supermicro did a 440FX board with both Socket 8 and Slot 1 and you could only use one or the other (even needed a separate BIOS). I had one of those as my first P2 board. It had PCI problems that caused most video cards to not work correctly.

I guess slotkets were not immediately an apparent option.

I guess you are talking about the M748LMR with only 1 pci and 1 isa slot

Your problem is probably the onboard video slowing down the system

It's probably one of the "XCel2000" boards... There were a few different models of those, all pretty similar. M748 was one, and there was also an M741 I think. Plus some S370-only versions, an Slot1-only versions.

The chipset on 'em was a rebadged SiS 620/5595, which wasn't a high performance chipset for sure, but it wasn't bad... I've played with other boards that used it, and it seemed to be in the same league overall as the i810. The video was slower than the Intel one, but it was still alright for 2D.

Those PCChips Xcel boards, though... there's something wrong with 'em. I've had a few of the Slot1 versions of those things come through the shop, and they were quite memorable. I almost suspect they disabled the L2 cache, but even that wouldn't fully explain the atrocious performance of those things. Making a Celeron 400 perform like a P200, yeah, that's a best-case scenario on pure CPU-intensive stuff... as far as the overall 'feel' of the system, an average 486 is more responsive (even running the same OS).

I had one such board: a PCChips M729, Slot-1 Celeron, ALi chipset. It was a
bad investment. This one was incompatible with several graphics cards. It
later developed random lockups when transferring files over a network.
DOS support was OK though, with the CMI8330 sound, but not impressive in
hi-res vesa modes. It had this heatsink with the "BXcel" logo, I still have that
item the rest was disposed off. I guess they tried to mimic Intel BX boards
with that name.
