To compound this, my backup X1000 that I bought second hand last year also had problems booting, constantly rebooting on the X1000 boot screen and therefore unusable, which is why I have been focused on new Classic Amiga projects for the past two months while trying to work out what the problem was!
This week though, I found the problem via the serial debug port on the Backup X1000! The Backup X1000 was failing to boot because of the Sata DVD drive, with an error occurring just after the detection of the drive. I removed the DVD drive from the system and suddenly everything worked and booted! I then swapped in a spare DVD drive I had and it worked fine too.
Wonderful! I have a working X1000 again (not my primary one, but I'll take it!)
Onwards and upwards - with Enhancer software released this week by A-EON I am keen to start using it again!
