Our version of VP/ix does not support partitions larger than 32MB.
This VP/ix came with ISC 2.2 and there is a fixdisk for it. We didn't
receive it, yet. However, I think that this fix was done to support
running MS-Windows 3.0 in real mode.

In fact, the current version we have doesn't even support more than one DOS
partition per harddisk drive !
Don't use ISC's fdisk to create more than one DOS partition. It will
let you do it but it will create multiple primary DOS partitions !!!

BTW: The restrictions for VP/ix are mentioned in the ISC manual !
But, the text printed is not very good and misleading. It reads like:
	Disk formatted with DOS 4.0x are not recognized by VP/ix.
That is not right in two cases:
	1. COMPAQ-DOS 3.31 supports partitions larger than 32 MB.
	   This is not supported by VP/ix.
	2. You can create partitions with less than or equal to 32 MB
	   with DOS 4.0x and still access those with VP/ix.
	   Of course, my comments regarding number of partitions per disk,
	   etc. apply here.

Hope this helps,
