WD 1006V-MM2 Problem

[Bob Leffler]

My system's floppy controller died recently, so I decided to replace it
with a Western Digital 1006V-MM2 controller.  My system is a Club AT
10Mhz (Model 1800b).

I've experienced several problems in installing the controller, in addition
to some run around by WD support.  I thought I would solicit the net's 
opinion before I start calling WD again in the morning.

Problem #1:

The hard disk does not boot from a cold boot.  The drive does spin up,
but the disk I/O light does not show any activity.  If you cold boot
to a floppy (both Xenix and DOS have the same symptoms), then warm
boot, the hard disk will then boot as normal.  (The hard disk is a
Seagate 4096)

I can warm boot as many times as I want without a hitch.  It is only
a cold boot that presents a problem.  

Is there a difference in how IRQ 14 is handled between a cold and
warm boot?

Problem #2

Xenix/286 2.3 will only create a partition via fdisk when the cache
is disabled.  The error message is "could not get device, parameters:
no such address or device."

Once the partition is created, Xenix appears to work just fine with
the cache enabled.  Does anyone have any experience with the 1006
and Xenix?  Did you experience similar symptoms?

Dos doesn't appear to care whether or not cache is enabled or
disabled.

Please email to bobl at edsews.eds.com.  I'll post a summary of the
responses once the problem has been resolved.

thanks,
