Default Re: Gemini 80-Bus System

Somethings just dawned on me... The disk I have just posted is a Bios 3.4 disk created with the BIOSFW.SYS bios file and whilst this is supplied with the MFB machines etc, it presumably isn't a 3.4 MFB bios but a 3.4 non-MFB bios.

My asumption is based on the fact that if I boot the disk in XBeaver and run the FORMAT utility it reports that it cannot run as it is not a Gemini MFB system. I also read somewhere that ...if you bought an MFB machine you may also have the BIOSMFB.SYS file..., suggesting that the others contain a non-MFB bios. I can test this by trying to boot my BIOS34 disk with a real 829 rather than my 849MFB.

So, I tried to create a bootable floppy disk using the BIOSMFB.SYS file (without winchester support for now) and I get an error that could shed some light on the disk image I am using.... or not... the screen shot is attached.
