I managed to get an ASRock AM2CPU upgrade card recently for my 939Dual-VSTA. 697A7C3B-96C6-49BF-A7E3-DE4113900378.jpeg Today I had chance to install, using a modified bios. The original motherboard CPU was a s939 Athlon 64 X2 4400+ (running at 2.2Ghz) with 2GB DDR 400, it’s now an AM2 Athlon 64 X2 …

Great thread! I use a Mystique 220 in my P166 MMX / Voodoo 1 machine. I had a Mystique in my first PC back in 1997 so i wanted to utilise that card again. I've only tried it with Tomb Raider so far (as the focus of the machine is the Voodoo 1 which was my first proper 3D accelerator) but I was …

Give FastDoom a try, i use it with my TI486SXLC-50 and it's significantly faster than regular Doom.

I’ve got one of these cases too! It was my first ever pc which I built in 1997. My bro recently found it in his basement. It was originally a k6-200 but now it has a K6-2 380 on a jetway j-542b baby AT so I guess it got upgraded in maybe 1999. I’m using a Mateox G400 and an AWE64 ISaA, and the plan …
Re: ET4000AX ISA - swap 80ns DRAM for 70ns?

Thanks for the info! I swapped the dram and, as you all said, it made no difference to the doom framerate!

ET4000AX ISA - swap 80ns DRAM for 70ns?
Posted on 2021-12-06, 19:04
Hi, I’ve recently got an ET4000AX Isa card and noticed it’s got 80ns DRAM Would it be a worthwhile upgrade to swap out the ram for 70ns DRAM? Looking at the jumper settings for the card, it’s already set for ‘turbo display memory access’ http://www.uncreativelabs.de/th99/v/U-Z/51718.htm I’m trying …

Hi again, I’ve installed an SX955 486 DX2-66 which can use L1 in WB mode. I’ve changed the motherboard jumpers of this SOYO SY-25P from regular 486 to P24D and the machine will post ok and I can enter the bios, however the boot process never gets further than the attached photo unless I disable L2 …

I think this amiga bridgeboard pc bios is unable to work with the LFB (aperture) on this ATI Mach 64, to be honest. Even though M64VBE says it's enabling the aperture, M64Diag then always says the aperture is disabled. If I get time to dismantle the 486 I'll try the ATI in that, but that's quite a …

Hi! How do I find the LFB address? Is the dos memory layout just displayed using the mem /c command? I have tried it without using the -ram command, no improvement. I’ve also tried the machine using with and without emm386 and with and without EMS ram. The VBD error is simply "Program too big to fit …

Also tried Univbe 5.3 - that enables me to run FdoomVBR too, but FDoomVBD again complains that the program is too big to fit. LFB is toggled on.

Just to follow up on this, enabling 0ws has significantly increased the frame rate of FastDoom mode Y on my Amiga Bridgeboard setup. I think it’s added another 10-15% fps No improvement in mode 13h but I think that’s to be expected given the slow Ti486SXLC

now that kixs has shown me how to enable 0ws on my ISA Mach64 I have tried mode Y FDoom again instead of using FDoom13H. Wow, big speed improvement! Previously I was getting 13.344 fps for demo3, now I'm getting 15.013! I guess the Mach64 likes using mode Y with 0ws, as previously it was slightly …

Also, the dram soldered onto my card is 60ns but my extra 1MB Dram chips are only 70ns. Is it worth me getting some 60ns chips, do you think? Would it provide a speed increase?
