I bench everything to "phil standard" because frankly it is the most accessible benchmark pack that everyone uses. Expecting someone to change default settings vs extract and go is ill-advised

BIOS is in OTP ROM 27C512 so coudn't be a a bad flash. OTP EPROMs don't last forever. I have one dead nVidia TNT2 with failed OTP EPROM . It is also possible to flip bits in OTP EPROMS by trying to program them again after the initial programming. Any '1' bits in the chip remain susceptible to …

This is targeted at people who tried to do something like the title suggests. What was your reasoning behind it? I'm thinking maybe to see what's the fastest system that can run Win98 and on top of that dual boot to XP. That would cover about 15 years worth of games. I'm currently considering …

Thanks. Ok, Kahneraz is picking everything except: - the two yellow mice (the one on top and one on bottom of the picture - the ISA LAN card - the ISA modem card - HDD They are still up for taking. Bulk-offload will be preferred. I will take the remainder, could use an extra serial mouse anyway :D

Even the motherboards that I mentioned with the ability to disable the internal controller don't have one, not even an unpopulated place where one can be soldered. What is going on here? Are you saying that they DO have a unpopulated DIP-40 footprint for a KBC but DO NOT have a footprint for the …

These cards have their own option ROM that scans for attached drives just like a SCSI card. The main system BIOS will still not show any HDD detected.

Ughhhhh what is going on. I'm trying to narrow it down to one or two SIMMs. I'm running 256MB in a Gateway G6 FPC / Intel VS440FX. There are no options to adjust memory timing. Anyone else ran into this issue? Could the modules be too high density or something? There is a jumper on the MB to change …

My board uses a simple LC filter with the 470uH/47pF giving a ~1MHz cutoff. This isn't a part of the design that a ton of thought went into admittedly, but it seems to work well so I stuck with it

Older drives are more sensitive to disc quality. This is also an issue with some 1990s game consoles. The Taiyo Yuden plant in Japan made high quality CDRs that are much more compatible with picky drives. For the last several years it was operating, Taiyo Yuden was owned by JVC and the packaging …

Pico rp2040 has IO quick enough to replace whole KBC providing both native PS2 and USB keyboard/mouse, maybe even with transparent joypad mapping. One plus would be ability to change board compatibility (am I correct in assuming its about how spare IO are routed to things like Turbo/A20?) in …

Yes but there is a problem. I still have the gerber files (and a few unassembled PCBs) but I lost the original design files in a hard drive crash.
