Yeah, I have a working install of 3.0 on my HD.
im actually formatting my HD now just for the hell of it.
if I pop in the floppy into the HD it does NOT recognize the disks.
my workbench "about" shows:
3.1 ROM
Kickstart Version 40.68
Workbench version 39.29
The floppy's arent bad though, because I confirmed they work in my A600.
The Floppy drive is working fine because I can boot my 3.0 Disks fine in the drive.
