Re: Correct PCI video init procedure during POST

Thank you. It seems that a hardware issue is being considered here, but my problem cannot be hardware-related, since everything either works or doesn't work on the same motherboard depending on the BIOS version. From what I can remember, it's related to the initialization routines. I base this on a …

Re: FastDoom. A new Doom port for DOS, optimized to be as fast as possible for 386/486 personal computers!

Quake wasn't using 'more modern' instructions. Also how quake renders is extremely different from how Doom does it - all the lighting is applied to a surfacecache, and that blob of surfacecache is where all the optimized spans work from. If you want to see that in action for Doom, there's Vavoom. …

Re: FastDoom. A new Doom port for DOS, optimized to be as fast as possible for 386/486 personal computers!

The main differences between the original Doom and FastDoom are these (as of version 0.4): How difficult would it be to add CMOV support (and possibly MMX+SSE) to Fastdoom? Hear me out please: Yes, I know this is supposed to be for old machines - but lately you have released new executables …

Re: Are these KZG caps bulging from the bottom? - Asus P5GD1 Pentium 4 socket 775 board

Kemet is now owned by Yageo Fixed. They bought them not too long ago. Shortly thereafter, they started selling Kemet-branded polymer capacitors.... One could draw the inference that Kemet polymers are Taiwanese -- that would mean decent quality. I don't trust Yageo for critical stuff, but I have …

Re: Are these KZG caps bulging from the bottom? - Asus P5GD1 Pentium 4 socket 775 board

No, the LMB is not part of the VRM high if it's 6.3V... VRM high is 12V, so only 16V caps are on it. It's part of the VRM low and I can prove it to you -- take a multimeter and check continuity between its positive lead and the positive lead of one of the short Panasonic FL VRM low caps. You will …

Re: Are these KZG caps bulging from the bottom? - Asus P5GD1 Pentium 4 socket 775 board

I've got some complications...there are no polymer 16V capacitors on Farnell UK for the VRM High caps. Unlike RS Components, where I originally found the replacements for those No, you're mistaken. Something like this fits the bill: https://uk.farnell.com/chemi-con/apsg160etd102mh20s/cap-alu-elec- …
