Check the path to make sure that you are copying the VT 2.0 files to the hard drive. Make sure the hard drive does not have any bad blocks. Make sure that the SCSI hard drive is less then 1 gb. If it is between 1 gb to 4 gb, make sure that the A2091 board has the rev 7 roms and the rev 08 WD chip.
BTW, most GVP boards are crap, so of course you will have problems with them.
