| subject: | Bloody ISA card |
DM> EMFBI, just to warn you - the serial and parallel cables that DM> come from the ISA card to the actual physical DBx connection DM> are not all the same - use the one that comes supplied with DM> your card. DM> Spent a wee while chasing that one down. Yair... I know. The cable the nice Chinese gave me with the VESA card does not match it. I went 90% crazy tracking it down; finally isolating it to the cable and checking it wire-by-wire until Brenton says: "There are two types, A and B, and no one knows which is which." ROFL! IFIIKE (I'm fucked if I know, either). WTF does EMFBI mean? Anyway, I got the bloody thing working. In the end I gave up trying to find the bad connection in the IDE pin header and resoldered the lot; I bunged in a coupla XOR gates (HC logic; the 4000 series is too slow), superglued on an IRQ11 copper track, and everything works! I have a max of four hard drives on the VESA card running Mode-4, plus the floppy, LPT1, games port, and mouse (I disabled the funny cable) and on the modified ISA card I run the CD ROM on address 1E8/IRQ11, plus LPT2 and COM3/4. I've got sockets everywhere! It only took me 20 hours. On my normal consulting rate I could have bought a new Pentium complete. The next one I modify will be easier... I'll just buy a sound card for $60. Regards, Bob ___ Blue Wave/QWK v2.12 @EOT: ---* Origin: Precision Nonsense, Sydney (3:711/934.12) SEEN-BY: 711/934 712/610 @PATH: 711/934 |
