-
- For those who are interested, my heavily modified wd driver for
- 386bsd is now available by anonymous ftp from barsoom.nhh.no.
-
- This is a modification to the config program to have it use such
- constructs as:
-
- controller isa0
- controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr
- disk wd0 at wdc0 drive 0
- disk wd1 at wdc0 drive 1
- controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr
- disk wd2 at wdc1 drive 0
- disk wd3 at wdc1 drive 1
-
- Information about the disks is output to ioconf.c, as well as the
- controller information that's always been written there. This means
- that logical ordering of disks is not tied firmly to the physical
- ordering.
-
- I've modified the fd driver slightly, to let it work with this setup,
- but the wd driver is rewritten quite a bit. It now handles multiple
- controllers and disks well (as the above example implies), and it
- also finally does bad144 style bad sector handling *correctly*! :-)
- I'm using it with the above setup, running two disks on each of two
- controllers, my disks do have bad sectors, and the thing works great
- for me.
-
- If you want to check it out, it's in pub/386bsd on barsoom.nhh.no.
- See the README file there for more specific information.
-
- Coming up next: WD formatting under 386bsd. (I need it for my
- secondary controller, which DOS can't see without physical mods!)
- (It may take me a while, though -- anyone else working on it?)
