It's also set to boot from drive 0, the IDE drive I think. Adding the SCSI "Hard Drive" may allow it to boot from there. I don't know what drive number that has though.

The thing is, the *configure boot option has no parameters to select a boot drive.

AFAIK you need two things to boot, the 'boot' option to be on and a hard drive to be set with opt 4,2 making it bootable.

Removing the SCSI drives from the equation I put the !BOOT folder into the root of the IDE drive and ran opt 4,2 on the drive having set the boot option. A couple of days ago, this worked and I was able to boot from the IDE drive and get all my customisations and drivers loaded at boot time. Then it stopped working as it had previously.

As I understand the boot sequence goes FDD, IDE then SCSI. If the FDD and IDE have no volumes set with opt 4,2 if the SCSI drives are then it will boot from SCSI. It's almost like the flag that says 'boot from IDE then SCSI' is being ignored, but I don't know why.

The SCIS drives do show on the 2nd page of *status, but the 'no hard drives' in the listing did have me confused too.

Seems the @rubber_jonnie's A5000 journey will last a bit more than expected...

I really admire your tenacity.

:bravo:

What happens if you type Shift-Break?

I'll try and see what it does. From RiscOS or at boot?

Thanks :)

It shouldn't really matter, it should do a warm reboot and try to run from disk, ignoring the setting in the NVRAM.

No different. It'll try and boot from FDD but not IDE or SCSI.

OK, so I've been testing the A5000 for a few days, and whatever instability was present previously has been fixed by replacing the latches, as it'll run all day with no problems at all.

I just need to figure out this boot issue, which is odd as it prevents a lot of the good stuff I did from loading and being useful. Meh!!

I do now have some CMOS IC replacements and given it is just 8 legs on the chip I may just fit a new one, see if it helps. If it doesn't then I will at least know it is something else.

OK, small A5000 update.

CMOS IC has been replaced, but it's no different, so it isn't that. It still tries to boot from floppy, but not from any hard drives. Stability is also sill there, so that's progress.

Need to see if I can figure out what is next in line for some attention, I feel it's fixable and I don't want to give up on it.

OK, so I think I've fixed the A5000, I'm now able to boot correctly, get my drivers and desktop customisations.

I was looking at the *configure options and one is *configure drive X, with X being the number of the drive to boot from. I changed this value to 4, my first SCSI drive and it is booting!!!

I am going to continue testing, but it's looking positive :)
