Any Extra Information: Purchased disks only on eBay.  No box, manual, or inserts.  All install modes seem to work fine except VGA.  PS/2 VGA works but VGA results in screen corruption.  Disks dumps fine with no errors or modifications.  Is it the old method of VGA access, or is there an undetected error on the disk?  Does the same thing on a real machine or in DOSBox emulation.
