Cool, love these bring-back-dead-stuff-to-life-threads :) Some thoughts: If you want to remove that heatsink, it usually works reasonably well to weaken CA glue by heating it, and twist the heatsink off. Just be careful to avoid melting the solder joints. It's said that acetone dissolves CA glue. In …

I don't have this, but i would likely buy one if one shows up for sale at my usual haunts. Looking a little like a sidewinder knock-off with with dualshock style twinsticks, it uses gameport rather than USB, which is odd for a dualstick pad - can anyone shed some light on it? Have you opened and …

I'm putting together a 486 system in the next few weeks (with luck). Assuming the motherboard works, it'll be 486DX-66. It has both ISA and PCI slots on it. I plan on sticking either MSDOS 6.22 on it, or FreeDOS; I also hope to get Desqview/X running on it. I've got an PCI Nvidia FX5500 video card …

And 320x200 256-color mode in general, it's way easier to spot with pixel/line doubling and also you test your monitor for proper upscaling. 640x480 and higher modes usually work well, …

Hotswap scares me (Xbox Classic flashbacks), I think I'll stay with Mendocino then since I own ZX and BX with 901MHz P3 and 1GHz P3. :D Hehe, it's a lot easier to hotswap a socketed DIP package than a TSOP, but each to his own I guess :) Edit: or you of course mean the HDD. That's also a lot …

The thing is I have compatible slocket1 but I have no idea how to patch BIOS to make it work.

I wonder if Celeron 766MHz will work and do I have to modify slocket1 for it? A Celeron 766 would be a Coppermine, as opposed to your 500, that is a Mendocino, so it's probably not as easy as simply plugging a slotket with a 766 in. First you'd have to check if the VRM can handle the load, dionb …

This to be exact. Try the bios you can download here . Compared the ID from the POST string (440LX-W977-2A69JM49C-00) to the one from your dump, it's the same. That image should work with your board. If it doesn't , we'll try a stopover on some version between the one installed on your board (1.4) …

Finished the hardware part of this. Except for the corruption problem (that I worked around by isolating the Write Enable pin until I got a better solution) it's working perfectly.

Just an idea. BIOSes around that time started to store data (ESCD, DMI) inside the flash chip. Maybe the corruption happens because it tries to write something but it fails because of "Unknown flash type". Also (and I might be very wrong here), couldn't this "dual bios" be implemented by using two …

The original BIOS behaves very strangely though, corrupting itself at boot. It'll overwrite addresses 0x0 - 0x7F (128 bytes) and 0x10000 - 0x1007F (128 bytes again) with FF, verified by dumping the corrupted image and comparing it to the original image. It works for one boot after writing the BIOS …
