D*am, you read quick!
Hmmm, I'll need to give that some thought...
...this is a Grub error, I presume..? (after the boot-selection screen, but before Amithlon starts)
PM me with:
Mobo, CPU, memory, gfx-card, attached drives(and how they are attached)
A run-down of how your HDD(s) is/are partitioned.
Contents of your AmithlonSYS partition (general layout will do, not an exhaustive list)
Menu.lst file you are using (and which entry you select)
If you're continuing to struggle & I'll see if I can track the problem down.
Keep at it. The first Amithlon install can be a swine to get working, but once you do...
...ClassicOS running @ modern speeds! Hey, isn't AmigaOS still bloody good when running on contemporary hardware?
