Hi all. I have an IBM Aptiva 2158 Series E. The stock power supply is, as the manual describes, "PC-98 compatible 95W ATX power supply." I popped the hood, and that's exactly what's in there. I was looking at this one: https://www.amazon.com/Logisys-Corp-Power-Supply-PS480D2/dp/B008MUD9IK/ Yes, 480 …

I copied UNIFLASH and the new bios file onto one of my socket 7 machines, then I pulled the EEPROM while the machine was running. Then I plugged in the EEPROM I sourced for the FIC motherboard, and flashed it using UNIFLASH. After that, I put the new EEPROM into my 486-VIP-IO2, moved the EEPROM …

Your Samsung module is a parity one. The most simple way to find out whether a module has parity or not is to count the chip. If the number of chips on a module is divisible by 3 (the Samsung module has 12 chips per side), your module supports parity. On the other hand if the count is a power of …

We do have that board with bios files here http://www.win3x.org/uh19/motherboard/show/4230 However I agree with cyclone3d : you should make a separate thread and upload photos of your board. This board has a battery that can leak and destroy traces. Remove it ASAP ! Also the fact your board beeps …

If the bios file you found are valid, then you can definitely update the bios. However if your ROM is really just read only or has to be erased with UV light, your motherboard won't be capable of flashing it (and it may not even have the circuit to flash a eeprom either) Now anyone with a …

Hi, I played GLQuake for years and years, and at that time I switched from P54C (Pentium 166 non-mmx) to P55C (Pentium 200 mmx). I remember very well the increase of playability and fun with Quake with new cpu, mostly for increasing frequency rather than MMX instruction set... In case check …

Too bad your's have integrated chips gone but that shouldn't be much of a problem, it's otherwise very nice and stable board. I'm using it even now and am very happy with it. I'm pretty sure I use non-parity modules, two modules of 8MB FPM RAM. I have used 4 of those modules without a problem but …

Ok, the easiest way to make images from the floppies is to use Winimage: http://www.winimage.com/winimage.htm The free version works fine. Before you put the disks in the drive, make sure to write protect them by sliding the little tab so there is a hole in the corner of the disk. https://www. …

Check if your motherboard accepts EDO or FPM memory. FPM should work in all motherboards. EDO can be a bit faster, but it doesn't work with all motherboards, for example it doesn't with Zida 4DPS (other than that it is a nice motherboard). It's also nice to have a PS/2 port for mouse. Also watch …

The problem is not a mechanical issue but unluckily an electrical one... 99% due to electrolytic capacitors. After 20-25 years they usually break down: all IBM ps/2 Intel 8088 with no hard drive and only 2 x floppy disks have today both FDDs broken and the problem (well documented also here in …
