This video is from 2011, but I think it's still good general advice. It might be overwhelming to think about everything he recommends anyway. https://www.youtube.com/watch?v=R_PbjbRaO2E In my case, I don't do electronics repairs on a daily basis and I'm not an expert. I spent more that 10 years …

It was something I learnt from PC Hoarder Patrol. Search Wayback for http://biostar-usa.com/ , change from the default 'Calendar' to 'URLs' (options just under the search bar). That lists all files archived from biostar-usa.com, which is lots (it says more than 10,000). Top right of the list is a …

Yeah, I've been looking on eBay but nothing really gets my attention. Getting an aluminum box may be a good starting point. Thanks

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 …

Hello All. I've been looking to buy an open case to test AT and ATX motherboards, but it seems that the only options available are for ATX and above. I was wondering if anyone has build one and can share some tips or ideas.

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 …

Bios file v4.50PG Awesome board you found there. Added it to UR. https://www.ultimateretro.net/en/motherboards/10195 Awesome!. Keep in mind that I modded it adding a socket for the Odin RTC.

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/http://www.biostar-usa.com/pd/products.htm Yeah, super weird, I was looking in WayBackMachine too, but didn't come …

Hello All! I just added this motherboard to my collection and can't find the manual or any info about it online. Does anyone has this motherboard's manual? Biostar MB-8500TEC ver3 I found some other variants of the 8500 series online, but the jumpers aren't the same.
