In general I recommend refurbishing older power supplies of good quality instead of buying new >700W monsters to use in retro PCs. The learning curve is not very steep, if you have basic soldering experience it will be very easy to work with single sided PCBs. I agree with you. Since it have ( …

Re: "Fake AGP" slots?

MSI made AGR, but that is a hack of AGP on PCIE. emulated AGP via PCIe - seems only MSI made those, unless you mean "they all cut PCIE down to x4 to use some of the lines for AGP"? It's confirmed that AGP Express at the very least uses undercover PCI trick. Some time ago, i have benchmarked the " …

Re: Is it worth to switch from 2.8 GHz Northwood to 3.0 GHz Prescott for Windows 98?
Posted on 2022-10-07, 19:01
it's 3.0 GHz, 800 MHz FSB, 84W CPU based on the Prescott architecture. Will there be any significant difference in performance between this and Pentium 4 2.8 GHz, 800 FSB based on Northwood architecture? Who's faster? No, it's not really significant. 3dmark2001: P4 3.0E (Prescott) is 2.7% faster …

No. The mapping is hardcoded. So5 has a single pin/bit (BF0) to switch between 1.5x and 2.0x, So7 has two (BF0 and BF1) to switch between those two and 2.5x and 3.0x as well. In P55C (Pentium MMX) the 1.5x is remapped to 3.5x. https://www.pchardwarelinks.com/cpuspeed.htm Here in these charts, …

once you set the bits for serial interrupts policy (S-IRQ) and set the dma mode to PC-PCI. I have tested it now half a day.

OK, thanks for the info. Too bad that it's not working out of the box. Then i have to go with DDMA. These modifications within the registers seem to me a little complicated. I guess it is the same problem like yours with the i845 platform.
