Re: Running GPUs and soundcards from different generations on one motherboard

I can't go with Window's XP. XP and 2000 runs on Window's NT and would require DOS emulation. I'm avoiding DOS emulation at all costs. Window's 98SE or ME are my best options, and I have just enough recollection of Window's ME to steer clear. The Radeon board that I'm looking at would be for the …

An nforce2 board is never going to give you broad DOS compatibility. It was one of the most DOS hostile boards I have come across in my testing. I was unable to get any sound card DOS drivers to work when I was testing mine. I'd also bet good money that a PCI2ISA device will not help with this at …

It's the board which can't handle more than 2GB. My buddy has the same problem on his KT3 Ultra2 with OCZ sticks. Underclocking or raising timings/voltage didn't help. We also found threads were people had the same problem with other sticks (Kingston, Corsair). Is this a common problem on KT333 or …

Do you have chipset drivers installed? If AGP drivers are not installed, performance, particularly for Windows 98 which has fewer built in AGP drivers. will tank.

Do you have any plans to add support for PCI PnP cards like FM801, ESS Solo-1 and YMF7x4 etc? Unfortunately, getting these working is much more involved than the ISA PnP setup done by UNISOUND. PCI does not natively support ISA DMA transfers, which is used generally for ISA sound cards. So your PCI …

If the optocoupler is sensitive enough, then it can act as a buffer for more problematic sound card outputs (like my ESS 1868) that don't always work with midi devices.

Lol, I feel I'm on a similar journey with my old i7-6700k after the last few years left unclean, as I disassemble and pack it away after replacing it with a new system. About the same amount of dust and dirt. Just from long operational hours in a higher airflow system and a few years of neglect is …

I've encountered the same problem with an ESS1868 card. Switching sound card to a Yamaha YMF-718 card fixed it in my case. Diagnosing this issue further. When I looked at the MIDI signal on the oscilloscope, you get a nice strong 0 to 5V square wave on the output when the ESS1868 is not connected to …

I very much prefer optical mice to ball mice. That means that I prefer computers with PS/2 interfaces, and I wire them up to a PS/2 port.

I just searched for 94 hex until I found the 94 in the right place (surrounding bytes are correct as per the usenet post). Then I change that byte, and add 94 to the final byte of the BIOS. Burn it to a compatible eeprom and install into motherboard. Note that a lot of the bioses at this time were …

Could just have been an iffy power connection. With 12 months of non-use, connections could have become slightly corroded and not making good contact. Simply reconnecting it (with the same or a different PSU) may have been all it neede.

b) A defective chipset that does "autostarting" like this might also fail to provide a clean reset, which also would reset the POST card. The POST card is apparently not being reset/initialized, as in normal operation it would not display " b", but "0b". Thus the "EC" code probably can be …

Your latest post code is EC .... and based on the list I posted earlier for this type of BIOS, it indicates a memory problem. Could also be memory problem in the CPU.

EC -> Have you tried different sticks of RAM ... also try them in different sockets. Still stuck on memory init. I can try to reproduce this error when I get home with bad or missing memory.

Also, the ISA slot you plugged the POST card into doesn't supply 3.3V, so that is why the 3.3V indicator is dark. It would probably light up if you plugged it into a PCI slot and turned the system on.

Computer won't post without memory installed. Ideally, for mimimal post on this motherboard, you want: a) CPU b) 1 x RAM stick c) 1 x PCI video card d) Your post card. e) Keyboard plugged in Without all that, diagnosing POST problems can be difficult. Your previous post codes indicate the …
