This very morning, while driving to work, I was thinking about PCI DVD decoders... I thought those are only good for Voodoo 2 RAM upgrade donators, because we would not see the day someone watching DVD's on retro PC. Oh god how I was wrong 😁

Just checking you have memory/AGP clock jumpers correct? https://kerenent.tripod.com/va503+.htm I've had a lot of trouble setting clocks with one of the MVP3 boards (Gainward).

Testing a pile of MFM hard drive bricks on WD1003V-MM2 controller. Seagate ST225 was the only one I could not get recognized in system, even though power-on sounds about right. Going to test it with another controller in Commodore PC-10. One of the disks is probably LLF'd to RLL because fdisk show …

I had once similar problem. As far as I remember, it didn't show (some?) digits in other position. I had to remove 7-segment display to find a burned track under. I guess someone had connected something in the wrong way or to wrong connector.. I don't know. Anyway, it works correctly now. I believe …

1st. My GA-5AX has Rev H of Aladdin V chipset. So it supports internal TagRAM. 2nd. Gigabyte designed it very well so it supports K6-III+ and K6-2+ cpus without any performance loss and without the need of any hardware modifications. They even published an adapted BIOS. 3rd. Power supply seems to …

I have DOS 3.21 in XT-clone (Commodore PC 10). Build one XTIDE-lite to ease file transfers. Original 360kB floppy drivers are not very handy for that... OK then, DOS 3.21 FAT12 supports single max 32MB partition. I can make about 20MB partition on CF card with fdisk and that works fine on Commodore. …

Well, you could design small PCB with 2.54mm female connector on back side which sits on jumper row. Then a normal th DIP-switch on top side. Long enough so that you can cut it to size you need. Maybe it should be asymmetric then you can rotate it if needed. Just a thought. since dipswitches tend …

Yes, that 2.0V jumpering is totally wrong and wont work. Look for the regulator datasheet and know why. Some modifocations are needed to go 2.0 and below.

I worked on socket 7 MS-5129 (v1.2) getting it ready for some action. MSI has done some nice forward-thinking. There is place for both PS/2 connector and RTC battery. This one had ODIN in socket. All I had to do was solder the new battery holder + solder PS/2 connector + drill ODIN battery pins so …

No solution here, just some bad experience. I had a long battle last summer with black painted case. I learned with DOT4 brake fluid you can remove some specific type, but it was not very efficient on this particular paint. It was good on some parts of golden drive bay covers. It's also nasty stuff …

To confirm, I have to have a psu plugged in and running to test that, right Power supply needs to be turned OFF. As ground point I have used mounting screw holes or molex plug black wire.
