I currently have an old 486 running FreeBSD 2.1.7.1 at home with 4 IDE hard disks attached (using local buss cards). The other day I decided to try adding another 2 by making a few hardware mods to an ISA IDE card. I have cut/rerouted the interrupt 14 line and tried various methods of changing the address lines (by swapping and by running a 74ALS04 inverter between the ISA address lines and the card). FreeBSD picks up the extra wdc OK but steadfastly then refuses to acknowledge theres a hard disk attached to the card. My question is 'what am i missing', it does seem to me reasonable that I can do this? Any ideas would be appreciated, I eventually want to get an array of disks working (2 are already using ccd).
