[net.micro.pc] Wang PC Questions

jayf@islenet.UUCP (Jay Fields) (06/26/86)

     The Wang PC Emulation Option manual, at the beginning
of Chapter 4, discusses Winchester Support.  In the last
paragraph on the first page, it states: "Wang PC and APC
systems can access files on nonpartitioned Winchester disk
drives in both Wang PC mode and in IBM PC Emulation mode."

     Our experience is that this only works on the 10MB hard
disk.  For some reason we can't get it to work with 30MB
hard disks.  Does anyone know of a fix or work-around?

     Also, we are very interested in UNIX/XENIX on the VS,
or even some interface which will permit rapid updating and
inquiry on the VS from a remote UNIX/XENIX system.

I did this on an APC with a 67mb hard disk.  You have to partition
the disk, and set up a partition as IBM and Wang accessible.
The kicker is that you can't have the partition for the IBM 
partition above 20mb or the disk may get zotzed.
And you may get hosed -- it'll eat the entire disk.
Your shared partition should be the first one on the disk.

This applies to BIOS version 2.50, I think, which was released 
7/85 to go with the first APC shipments.  I hear that version 4.0 
is coming in september, with millions of improvements, including
a lot more IBM compatibility.  There may be versions in the 
interim where the placement of the Wang/IBM partition doesn't
kill the disk; I don't know.

Also, it should be noted that partitioning is no big deal -- 
it only takes 64K on the beginning of the disk; the partition
management software, which you should only use once, can stay on
its little floppy.
