Means yo' is in deeeeep trouble. Seriously, see below.

| Standard serial board COM1 ...
| Parallel port ...
| rootdev 1/40, pipedev 1/40, swapdev 1/41
| disk[D] drive 0: cyls = 58, heads = 64, secs = 32
Unless you have a truly bizarre disk, you have clobbered the hard disk
description. I don't think you have 64 heads or only 58 cylinders. You
*may* have clobbered the description of the disk with your driver, but
that's only a guess. I did something similar with a power spike.
You could try to reset the drive paramaters. I don't have manuals
handy, but I think it's hdinit that will do it. Boot from your backup
floppy boot disk and try that. If you don't have a floppy boot you might
be able to use your N1 disk, but I haven't tried it.
Save what you can. I doubt that the disk will completely recover if
you reset the type, but you might be really lucky.

When writing drivers keep **lots** of backups.
| When I'll finish the driver I'll let you know (anybody interested please
| mail me) and will make it available to anybody that want to use our
| CD-ROM controller.
Be sure to get it out in beta test to a few sites with a lot of serial
lines. Preferably sites with dumb serial cards. Beating the interrupts
tends to shake things out. When the driver is well debugged I'm sure
everyone would like a copy, if only to study.
The Xenix device driver manual section is pretty helpful.
