I have some '552 cards that are total crap (they'll actually crash the system they're in after a few minutes), but I have a card with two 16C550CP's on it. Can you send me _all_ of the numbers off the top of the chips? I can't remember offhand whether Startech are kind enough to print date codes and the like on their parts, but it would be useful to compare them with some that are known to work. ST16550CP H9509 Just on the off chance; what else do you have in the machine? And for the record, what are the other chips on this card? I presume there's Just an Oak VLB video card and a fairly generic ISA IDE/2S/1P/1G controller. some decode logic of some sort : it might be helpful to know what else was hanging around there. There are 3 GD75189A and 2 GD75188 chips on the card, plus some random TTL logic. From: Michael Smith <msmith@atrad.adelaide.edu.au> Date: Thu, 27 Jul 1995 19:10:24 +0930 (CST) I should have also asked : Are the parts socketed? (You could try swapping in a 'real' PC16C550D (a NatSemi part) and comparing notes. They are socketed, but this is getting kind of ridiculous; I'd rather just return the card and get one that works with FreeBSD. Maybe this is a stupid question, but: it is possible to add two serial ports to a PC that already has two, right? Tim
