Also, My SB card doesn't produce sound after all, even though it goes through a complete sbemu initialization with qemm, probably due to the lack of support for the ICH7 chipset, so I'll take it out and just use the onboard card, which produces really great sound. FWIW, it's not related to the ICH7 …

I have a similar question. While 160W of PicoPSU should be sufficient for any typical setup, even with fast 3.5" HDD and PCI video card, but I'm planning to use it with a laptop PSU rated at 100W. Will it run at 100W, with integrated graphics and IDE to SD adapter? That's more than enough. I used …

I tried SBEMU for the first time today, on my PC with Intel 945G @ICH7 and two cards, onboard Realtek AC97 (ALC882) and Creative SB 128 PCI CT4810 (5580). Interestingly, sbemu recognizes SB card as an Ensoniq ES1373, even though the card has the markings I listed above. The Realtek onboard card …

I took the card out again, cleaned it more thoroughly with eraser, put it back in and the Vendor ID correctly recognized the number as 5880! Nice work. Is the solder blob still there? I'd try to clean that off as well, it just doesn't look right (if it is a solder blob). Hope this gets resolved, …

For some Dells, at least the XPi CD (Pentium [MMX]), CPiA (Pentium II), and C500/600 (Pentium III), it is the reserve battery used to hold the contents of NVRAM and power the RTC. It's supposed to last for 40 days from a full charge. They do not have a separate 3V "coin cell" battery like desktop …

Found this old thread (albeit in the DOS forum) discussing the same issue on 2017 and newer CPUs (including AMD) and basically says there are no VGA or 8-bit VBE modes supported in BIOS. A tool to dump the VBE modes supported, like PCPBENCH, would confirm that. Given the limitations, I suspect it …

Well, VINFO doesn't report any video modes on HD 500, but there's this "AdvanceCAB" set of utilities, available here: http://mirrors.arcadecontrols.com/AdvanceMAME/cab-download.html The inlcuded utility called VGA.EXE can detect these modes on the HD 500: report7.jpg However, after loading this " …

A good start would be to list what VBE modes, if any, the video BIOS claims to support. There's a tool called VINFO, unless someone knows of a better one.
