Does a P100 really require that much more power than a P90? No. P75 has 8 watts P90 has 9 watts P100 has 10.1 watts Unlikely that this makes much difference. It doesn't look like much but the P100 at 10.1 watts crosses a 3 amp threshold. The Overdrive upgrade requires 5 amps. You can see where …

edit: Additionally, the PBAs that support the 100mhz CPU will support the 200mhz MMX Overdrive processor. This is specifically because of an upgraded voltage regulator on those boards. I suspect this is probably the difference between the 75/90 and 100 PBAs as well, and even if a 100mhz chip "works …

"NRM/CLR". Set it to CLR (2-3). It's completely fine for using, unless you need correct date/time (who needs this on a retro PC anyway?). All default BIOS settings are also fine, I did not find any setting I need to change. Even IDE is auto-detecting by default. Yes, completely fine for using, …

This is interesting. The PBA number on this Plato board is 541277. According to the manual, it will only work with the 75 and 90MHz Pentiums. But when I put in a P100 and set the jumper for 100MHz, it goes into BIOS, shows the correct speed there, and boots from the floppy just fine. IMO, that fact …

You'll never need more than that 4MB Millennium for pure DOS gaming (for VGA software-rendered games. You can add a Voodoo2 for the handful of DOS glide games you might encounter). still, a voodoo 2 with a pentium 60 seems overkill Any 3D card is probably overkill for a P5-60. I personally used a …

Looks like a workaround: http://files.mpoli.fi/unpacked/hardware/rom/intel/platord.exe/readme.txt What is the driving purpose behind updating the bios? Do you have release notes for the newer intel version? It won’t change the HDD support. What are you after? I thought it's just a good practice to …

I would not use it with any gear I cared about. Get a refund. These cheap fake cables are legion on ebay. This cannot pass through any joystick signals, so it's a pointless cost increase to even have included it. The IC is meant to be a buffer between the MIDI device and the sound card, sort of like …

The killer cards were Millennium I for 2D and Voodoo 1 for 3D. Rage Pro was a good compromise in the middle. Riva 128 came later and its 2D sucked ass IIRC. My Millenium (Gateway OEM) got me all the way from 1995 to Baldur’s Gate and AGP. I toyed with M3D and Voodoo along the way but really wasn’t …

The cheap price of the Gotek is its main appeal. but your right, once your PC/Network is up and running it doesn't get used much but evey now and then you need FDD for HDD drivers for XP, a boot disk or, sneekernet on later machines without CF cards. Plus finding something on 1 known good USB is …

the harder part would of course be creating an image of said key disk. There's the rub. The PC community has the toolkit (kryoflux, teledisk) but not the image format. Unlike, say, the Apple II guys with their own flux imaging and .WOZ image format that can reproduce pretty much perfect disk images …

I ended up making my own breakout box because I wanted to integrate a joystick y-splitter without a rube goldberg chain of adapters. I don't know how to spot a legitimate breakout cable except maybe by the girth of it -- if it looks like there can't be 15 conductors inside the cable jacket, then …

It's a supported configuration. The Midi in and out use pins that aren't necessary for joystick operation, so you are free to pass all the pins required by a joystick. Most likely issue is that the joystick port on your MIDI cable is miswired or not wired at all. I've seen cheap "MIDI game port" …

Demystify the Gotek for me. Does it support multiple image sizes at once or is it locked to a particular size (e.g., 1.44MB)?
