Checking my Dell AL440LX board, it is missing those components entirely so I can't suggest values sadly. My current guess though is that they're connected to the FAN2 header on the mainboard since only that and the Line-In header are not populated on mine. That makes sense since those are power …

So, I think I hit the jackpot. I've only ever found one 486 board in my area. Never seen anything older that wasn't going for a crazy high price. But the other day someone posted this on FB for FREE! mobos.jpeg They both had Vartas that were exploding, but I think I got really lucky. The top board …

The RAM clock is too high for 50ns chips, they've got to be 35ns or lower from what I recall. The fault is less likely to be the RAM chips themselves but the QFP chips often have weakened solder and loose legs so some lines that would connect to the RAM are disconnected. I've now fixed 5+ Voodoo 1 & …

Great that you've got it working now :) I wouldn't have guessed a setting in the BIOS could break that. Maybe it's like my Portege 610CT which when the BIOS resets will set its IDE mode to standard instead of LBA so its own factory installed hard drive won't detect until that's reconfigured. …

Wow the screen on that one looks great!

It's got some empty pads at R22 and R24 that look like my MSI MS-6168 v2 board - with options to connect Chip / Bank Select either to the A10 address line (R22) or Chip Select (R23), with another pad (R24) to hook Chip Select on the RAM …

There's evidence of corrosion in a few spots near to where the caps have leaked. Look at IC8 M51132L, I assume that's an amplifier or something? The solder joints don't look good and specifically the trace by the letter C of IC8 Similar thing with some of the pins / traces on IC3 as well, that …

Can also confirm that a Ti 4200 can run with a passive heatsink. I'm using a Zalman fanless cooler, which is basically two giant heatsinks connected via a heatpipe. Also have a couple 140mm intake fans that help push air towards it for good measure. Good that you've got some air blowing over it, …

Yep, that should work 😀 I can definitely run most of my laptops using a 65w power bank and the cables I made. That cable works the same way as the ones I made and will put the DC jack power output to 15v when plugged in.
