Replacement AT Mother Board Specs

[bettablue]

As most of you all know, between hospitalizations, I've been working on building a new tweener. Well, the Mother Board that Jimmy first sent me proved to be bad, so he graciously got me another, which arrived a couple of days ago. Although I've just been released from the hospital on Sunday, It wasn't until today that I felt up to working on the computer. The replacement Jimmy sent me was one he found on E-Bay. It was sent as a guaranteed fully functioning board. Jimmy bought it from a seller on E-Bay, and had it shipped directly to me. Now, I'm having some trouble locating the manuals and possibly chipset drivers and BIOS upgrades. The most important thing right now though is where to locate a PDF or equivalent manual.

The new board came with a 200KHz Pentium processor and 1 Gig of RAM. I was actually hoping to get a slower processor, like something in the area of 66 to 755 KHz. If one can't be found at a reasonable price, I guess I could under clock the processor. I want the slower speed in order to test some of my original DOS and Windows 3.1 games, of which I have more than a few. This is just one more reason I need the proper manual.

So, does anyone here have a link to the documentation I need so can configure my new mother board?

Thanks much everyone.

A bit of detail might be useful. Is there an FCC ID or model no. screen printed on it? Some here might recognised it from a a good quality picture.

I don't know, Thomas, that has to be the slowest Pentium I've ever heard of.

What's the model and make of the motherboard?

Sorry Brain fart. Here is all I know about the board...
The make/model is

QDI P5I430VX 250DM Explorer II Socket 7 AT Motherboard

I've been able to locate the make and model on the web, but everything comes up as either Chinese, or Japanese, or something similar. It has the 200 MHz Pentium processor already installed with a pretty small heat sink/fan combo. On the back is a small white sticker that says "QDI World Class Main Board. And yes it is another AT style socket 7 unit. Lastly, the battery is of the flat circular 3 volt disc.

Pictures would be useful. Why not just hook everything up and turn it on to verify the amount ram and ensure it functions ok? Then worry about underclocking.

This Mother board QDI P5I430VX 250DM Explorer II Socket 7 AT Motherboard is really quite heavy in comparison to some of the other boards of the similar size.

I hope my last two replies make sense.

This it? http://www.motherboards.org/mobot/motherboards_d/Legend QDI/P5I430VX-250DM+Explorer+II/

Details etc? http://stason.org/TULARC/pc/motherb...NC-Pentium-P5I430VX-250DM-EXPLORER-I-286.html

Bios updates? ftp://ftp.hs-merseburg.de/pub/hardware/mainboard/qdi/bios.html#e2

That is indeed it. But none of the links for the manual, BIOS upgrade, and drivers work.

 

[Caluser2000]

Try using google the see if there are other links available using the file names listed in link 3 for the bios updates.
Looks like there's two versions of the board with one being a "SpeedEasy" so be careful on the bios updates. Max ram seems to be 128megs.

How's this for the manual?

You could also start from here: http://www.elhvb.com/mobokive/Archive/Qdi - Legend/

Some BIOS files seem to be here: http://www.elhvb.com/mobokive/Archive/Qdi - Legend/bios/socket_7/index.html (vx_ii or XPLORER_II folders)...

 

[Caluser2000]

No DIMM slot on that one Chuck. From iulianv links http://www.elhvb.com/mobokive/Archive/Qdi - Legend/manuals/index.html#IDXPLORER_II-

I'm not familiar with how QDI did their naming, but there are a bunch of files on the Wayback machine (archive.org) for qdigrp.com.

Would the VX II be the same board? wayback page here

 

[Caluser2000]

Looks like the same setup as per the Explorer II manual. All bases covered by the looks.

I have a Pentium 75 with heat sink & fan if that's of interest.

 

[Caluser2000]

Disabling all the cache ram will drag the cpu performance down. Using slower 72 pin simms will bring it down further I'd imagine.

Thanks again everybody. I don't know what I'm doing wrong, but my searches never turn up with the results you guys seem to pull up. I've saved the manual, and I'll be ready to start installing and configuring this board in my tweener.

I also found where I can adjust the processor CPU frequency, so I won't need the 75 MHz processor. Thanks though.

I'll post here again if I need something in addition, but it looks as though everything is covered for now.

Good catch. Mine does not have the "Speed Easy" option or whatever that is. And you are also correct in the amount of RAM that's on board. There are 4 sticks totaling 128 Megs.

Thanks again.

Looks like it'll do exactly what you are after Thomas.
