phk 95/04/14 15:32:00 Modified: sys/i386/isa wd.c Log: I commit this for Bruce, who has serious connectivity problmes pt. This should NOT go into 2.0.5 /phk Support disk slices. This involves mainly replacing inline code with function calls. Support for ST506 drives is temporarily broken since the `setgeom' arg to dsopen() is not implemented completely enough to use. The `setgeom' arg will go away and ST506 drives will be supported in another way. A large amount of dead code is left in wdopen() as a reminder of the problems here. Close the device in wdsize(). Open tracking was broken on all drives with a swap device. Remove support for soft write protection. There are no ioctls to set it. It was used to disable writing to unlabelled disks, but we want to support writing to foreign partitions on unlabeled disks. Use generic dkbad routines to do about 2/3 of the work for supporting bad144. Improve disk statistics: estimate 4MB/sec instead of 8MB/sec for the transfer rate (ISA max is 4MB/sec, old IDE max is 3.3MB/sec); fix dk_xfer[] (it counted sectors, not transfers); keep the estimate dk_seek[] = dk_xfer[] (was sectors, is now transfers); only count words actually transferred (the count is still too high after a failed write and after retries). Remove wdxfer[]. Fix indentation in wdattach(). Fix resulting botched printing of the disk size for ST506 drives. Print the disk geometry less cryptically.
