This is what I am using an adapter to convert ATX to Dell style for this. But still not perfect as I tried number of video cards, Geforce2 and 4, Asus TNT2 AGP. No display, but can use PCI video cards with this. I can resolder the dell style and shift the ATX connector over to ATX standard, remove …

I knew what I am going into this, since I had HX motherboard and know these features are. I had a baby AT Asus P/I---- with HX chipset and Pentium 100 in 1995 or so, came with 16MB of BEDO memory (pair of 8MB which used to cost 700, more than board and CPU combined!). Preferred ATX form factor …

Does not have to be a coil, it will look like donut, spool type or grey block, also tap on the each capacitor. If you tap or press on each when you get right one, you will know instantly.

Who specified those XT/AT PSU connectors should be shot (IBM why? you are known as high quality maker but strange, why?). Very chummy design and cheap. Best fix is splice onto good PSU from new stock extension or ATX to AT adapter cable harnesses from ebay. Soldering and heat shrink tubings. Cheers, …

Actually look back to the XT and AT that begun that oddball less than actual memory reported when 1MB or more memory is used: 8088/8086 is 1MB addressable range, the missing bit is upper 384K is reserved for mapped i/o ranges for expansion cards. That why 640K max. Same with 286 if using 1MB total …

386SX is 16bit data path with 24bit addressable range for memory allocation. So this is same limitations as 286. 16MB max except 386SX gives you a way to run 32bits enabled software. Slowly. Cheers, pentiumspeed
