Ah yes, the famous Guru ROM, as rare as Martian sweat these days.
Had a look around, plenty of people have the ROM code for making EPROMS, but all useless without the mini adaptor board and the GAL chip/code.
The GAL seems to fool the controller into thinking the 27256 32 Kb ROM is split into 2, odd and even parity sections. Apparently this does something to alter the apparent address space available? Is this correct?
Does anyone either have a Guru ROM upgrade for a GVP HC8+ Version 2, revision 2....or another way to get my 18 GB 10,000 rpm HP SCSI drive fully used by Amiga?
If not, I might just format/partition it to the MAX 3.37GB allowed by the OS and forget about the rest (14.63GB) of the drive....seems like a waste though.
Thanks for all your replies
