Hi! Should be no issue if standard card and the mainboard being upgradefriendly... FreeBSD should use the sym driver, then it should also recognizte the card, if the mainboard will fire the Symbios up correctly. If it leaves the onboard controller as controller #0, you'll have the check wheter in BIOS setup of them, the controller #0 AFAIR has to have a lower adress. > >Also, does anyone know if I can put ATA disks in this machine?

Could I put a 16Gb ATA drive in it? > Do not know this in this particular machine, but in general, most machines have also IDE onboard, and if not, you may spend little money and put an E-IDE card into it. some are available for about 10 U$ (20 DM here in Germany), which will utilize the mainboards BIOS. This would ba a problem, because the old BIOS back then (I remember an Intel Plato board with the first P90 those days (95)) that only allowed IDE up to 2 GB. Later they were happy with 8 GB limit, but thats all you can get out of that. Or you invest some more money for an IDE controller with an own BIOS, like some of Promise or so... there are even some cheap cache controllers that you can pick up used. I'd also check ebay or so for some thingies. Also then you have really to worry about booting issues, because IDE usually comes before SCSI. the BIOS switch to put SCSI first has been iinvented later. Old ( I remember an NCR 810 card) controllers came with a special jumper that lowered their adress below that of IDE controller, so that they could boot up first.
