That's a tough one - this capture of the Biostar USA page skips right over that model; maybe it wasn't sold in the US, or was OEM only? https://web.archive.org/web/19970620073836/ht … pd/products.htm

Try here (includes v3 specific jumpers) - https://web.archive.org/web/20010209101446/ht … EC/menutec.html

Yeah, super weird, I was looking in WayBackMachine too, but didn't come across the link you shared. Good to know, Thanks.
I got the board for cheap so I didn't bother trying to find the manual first.
I have no idea if it was OEM or what since I got it on eBay.

Thanks again!

Awesome board you found there. Added it to UR.

Awesome!. Keep in mind that I modded it adding a socket for the Odin RTC. If you look closer at the picture, the RTC looks a bit higher than it should.

I have around 10 more socket 3 and 7 motherboards in my collection, PM me if you are interested.

Yes, that looks about right. I haven't tested it yet though.

I did search there but it didn't show up. What was your search keyword?

There are more jumpers that are not documented and some have charts printed on the board:

Jumper# / Pins / Current State
JP1 (4) 3-4 (No info)
JP2 (4) 3-4 (No info)
JP5 (3) 1-2 (No info, might be the Bios voltage as per continuity test: 5v / 12v)
JP10 (3) 2-3 (Tage Size, as per chart printed on the board)
JP11 (2) Open (No info)
JP12 (3) 1-2 (L2 size, as per chart printed on the board)
JP13 (3) 2-3 (L2 size, as per chart printed on the board)
JP14 (2) I wasn't able to find this jumper (Pipeline, as per chart printed on the board)
JP19 (6) Open (No info)
JP20 (4) Hard Wired ((No info, might be CPU Voltage)
JP22 (3) 1-2 (No info)
JP27 (3) 1-2 (No info)

See attached doc with updated info.

Great work ! You are the archive master 😀

Curious What format is that .doc ? Cannot open it for some reason using MS Office or Wordpad (win7). Hex edit shows PK as the header so is it zipped ?

I use Libre Office. Here is a zipped docx file, let me know. Thanks

Thanks that opened ! Yeah I usually just save the archive pages as .HTML and then quick edit to add/fix. Think any computer from Win9x up can open a .html if it has no java or odd stuff...

Found reference to a couple of older BIOS versions here - https://web.archive.org/web/19990220172430/ht … ec/tec-bios.htm

Looks as if your original was TEC0607.BIN from June 7 1995 (sadly no trace of TEC0831.BIN)

Interesting! It looks like the "newest" Bios version is i01bw429.bin, as previously posted by snufkin.
I still haven't test the Bios, will report back when I do.

This is an odd motherboard, it may be one of the earliest socket 7 that Biostar made. It doesn't have a ps2 mouse port which I find odd for a socket 7, and very limited CPU support.

Yeah, I did look again but this list (pretty much the same as the jumper manual) seems to be it for this board - https://web.archive.org/web/19990220164452/ht … c/cpat85tec.htm
