But I wonder how I can enable L2 cache . There is jumper setting on the mainboard and installed 256kB (9 KM68257CP-15 32K*8 Bit, including tag ram) but it was not working originally and still no option to enable it. Have you tried external tools to check L2 cache? Attached cachechk, pretty much the …

Hello Thanks for the reply. Could you let me know where the bios is? I have chip programmer for bios flashing and think worth trying.

Hello. I wonder if there is MR BIOS for OPTi 82C802/82C601 486 mainboard. Hi! Well you seem to have a very tricky case. First, I don't think I ever saw any mentions of OPTi 82C802 in MR BIOS docs. In fact, it seems to be a pretty rare chipset — on TRW there is only one board with it . We do have …

A bit of a heads-up for the person maintaining the Unicore BIOS repository, and anyone with a Tekram P5V30-B4 motherboard. The Unicore 2A59GTG9 BIOS is actually broken: it doesn't correctly assign PCI IRQs beyond the first detected PCI device, so everything past the first PCI device gets 'NA' IRQ. …

My turn to test a C3 Nehemiah 1200 with a C5P core. It's running on an Asus TUSL2-C, 512MB PC133 and Windows XP. I first used an eBay IDE to SATA converter (as you see on the photo) but it's really an unstable piece of junk, so I switched to a Promise SATA300 card. Interesting! I'm using a C5P core …

I've been able to find four names so far: Mike/Michael Meisner — mentioned as "the sole proprietor of Microid Research" in some sources from mid-90s (probably prior to their sale/merge with Unicore) Jason Raza — often listed as "contact at MR BIOS" on Usenet Rhod Williams (?) — mentioned as working …

Someone might correct me, but I think a lot of Pentium 4 motherboards with SIS chipsets have universal AGP. This one in particular is pretty common. The trick is that people often installed these motherboards in full ATX cases, so you might want to check for old office computers in your area. Of …

Had an issue with an Elsa Gloria L videocard (somewhat early OpenGL card for workstations). I got it from a recycler and it apparently was lying under something with a leaky battery, so the acid covered several legs on the main chip. When I tried to clean it and run on a 440BX motherboard, it didn't …

Nice build! How are you liking the EWS64XL so far? Don't see people using that card too often lately. I own one, and it's a pretty cool card, but damn my headphone jack is noisy 😀 Maybe I'll give it another go after shielding the cables with tinfoil or something.

And, although it ended up being the incorrect image for my motherboard, there's an image in the "MRBIOS Big Bundle" that is missing every other byte. Specifically, it's in V002B406, but the "target5" download contains the complete copy. There could be more examples of this. Just something to …

However, the earliest Intel one are for 430FX. 430LX/430NX have not been found or even mentioned anywhere. Same goes for Unicore Award . The only 3rd party BIOS upgrades for 430LX/430NX …
