[comp.os.minix] 1.2 AT drivers still seems at little ill

Leisner.Henr@xerox.com (Marty) (09/16/87)

I now have a 1.1 system up and running on Aztec C and want to get my
hard disk going so I can have a useful system.

After the bootblok transfer control to fsck, the controller status port
(1f7H) is 0 -- the disk controller is totally idle.

After booting the system, execute win_init() which executes com_out(),
which calls drive_busy() which fails automatically if RDY (ready) or SC
(seek complete) is 0.


I'm currently playing around with the driver (I have the specs for the
WD1002-WAH in front of me and it seems to agree with the bios).  I
played blindly with the winchester driver to get my home system running
of the hard disk, now I want a driver which runs reliably on both 6 and
8 Mhz ATs.  The way the driver boots up (if you can send a command to
the controller, set number hard disks to 0) is not very robust.

I went though this in May, and I'm going through this again.  Does
anyone have a really good AT driver they'd like to send me (uucp
please).  Any pointers to good discussions about how these WD1002-WAH
boards work would be nice.

Has anyone been able to use the at_wini driver with newers ATs?  It
seems like its really close except for some sticky (:->) bits.
