[comp.os.minix] WA2 Problems

schmitz@uiucdcsb.UUCP (04/30/87)

Has anyone gotten MINIX running with hard disk on an AT-clone with
the (usual, I'm told) Western Digital WA2 controller board?  The 
controller chip looks like a WD11C00C-JU.  I've made the changes
suggested by Larry Hubble, and the status has changed from "not working
at all" to "somewhat working".  I can make a file system and mount it.
However, all attempts to use the new file system like "mkdir", for 
example work, as long as you don't mind lots of messages printed on
the screen 
	"Winchester wouldn't reset, drive busy."
Actually, it sounds like the drive is being reset, every second or two.
The message is printed in w_reset as a result of a call to drive_busy.
The culprit could be some controller bits tested in drive_busy which
aren't approproate for the WA2.  Does anyone have documentation that
tells whether drive busy is testing the appropriate bits?  Thanks.
