Looking for a 486 bios, Intel Classic E-series
Posted on 2022-11-18, 19:25
I've got this motherboard, but I'm missing the bios, and the bios files distributed by Intel only supports upgrade of an existing matching system, and the files that are part of the upgrade package cannot be combined to a working bios. I was told "these unfortunately can't be concatenated, intel did …

So is the c1 c2 placment reversal not causing a issue here? It’s actually the people building them putting them in backwards only? Sounds like it. I can see that happening when orienting the capacitor based on its markings and ground, because usually ground is the most negative end, but not here (- …

I was able to clock it down to a 4x multiplier my 366 device (goes up to 5.5x) using the DIP switches. With at 50MHz FSB, it runs at 200MHz in an old Socket 5 motherboard 😀

Re: Orpheus Soundcard: a new DOS soundcard with SPDIF/OPL3/MPU support

Question about the SPDIF output: does the OPL3 sound pass through it? Also, what is a good way of recording SPDIF output from the Orpheus? A Sound Blaster live/audigy/X-Fi with digital coaxial (SPDIF) input I know about, but I'm having trouble getting one. Are there other sound cards I can use?

Thanks! That's well written documentation. My takeaway is that switch 1-2 can be used to underclock the CPU, and overclocking it requires a hardware mod. Also, replacing it with a k6-iii or CPU using <2.2v requires hardware modding.

The documentation you linked to says something about removing the CPU to access 6 dip switches. I wonder how that can be done. I only see the 2 dip switches on the vrm board of the adapter.

I'm thinking of future repairs of motherboards and other equipment. Are some old parts getting more and more difficult to find? I think so. For example, I've bought some ISA-slots, RAM for ISA-cards, 5->3.3v voltage regulators, DIP cache chips, DIP-28/32 EEPROM, IDE-cables, floppy-cables, and AT- …

Thanks, then I'll just overwrite, and possibly modify the "rom" to use the original PCI ID. Or just modify the Windows driver to recognize the Gravis id.

I gave the bios chip a third run in the TL866II programmer. By disabling BOTH pin detect and check id in the Xgpro software, I was able to read the chip (id reads as 0xC211, but should probably have been 0xC21A according to datasheet). I don't trust this chip, and I'm happy about replacing it. …
