The drive works, but I can't boot my Mac Plus off my SC80

[krye]

I'm trying to boot my Mac Plus with my SC80. Termination is good and the drive is detected by Lido. It's not the stock 80 MB drive, it's actually a 700 Meg drive. I formatted the drive and rebooted with a System 6.0.8 disk with the Lido INIT.

The drive mounted successfully:

I then ran the System 6.0.8 installer, successfully:

I then used Lido to set the interleave to 3:1:

Once I was back at the desktop, I opened the System folder to bless it. There is a System icon on the System Folder.

Whwn I I reboot the Plus and I get a happy Mac, but it stops there. Just the happy Mac. It doesn't boot any furthur. I also tried to Apple HD Setup utility but it couldn't format the drive. Anyone know what I missed?

It could be lots of things, but the first thing that comes to mind is, did you ensure the drive was a 'bootable' one when you formatted it?

I use FWB Hard Disk Toolkit to format my drives and there's a checkbox you need to check to make it a bootable drive. Automount is usually checked by default, but Im not sure whether bootable is. Worth checking on this before you try anything else.

Hum, I'll have to check that. I don't remember seeing an option in Lido to make it "bootable". I thougth it was bootable as a function of having Sysytem 6 installed. I'll have to check tonight when I get out of work.

Can anyone else confirm? Is there an option in Lido that has to be specified in order to make a volume bootable?

I actually just came across another post here of someone with the same exact problem:

After much trouble the poster found that it was a actually a SCSI bug in the rev B ROM that prohibited his machine from booting from the drive. Swapping the ROM to rev C fixed it. I hope that's not the case here. I'd sooner just boot it off a floppy and mount the drive with the Lido INIT.

Sorry, that was a typo, I gets stuck at the question mark, not the Happy Mac. And the question mark isn't flashing. I just tried Lido again and looked at the partition map. A driver is installed. The interleave defaulted back to 1:1. Being 700 Megs, it's modern drive, so it probably has i's own cache. I'll try and repartition the drive with a boot volume of 40Ms and see how that goes.

As far as the ROM, bug, that's probably no it. I found an Apple support doc that stated they only produced about a month and halves worth of machines with that bug. This is a Platinum Mac Plus, so it shouldn't be of the same vintage as those Macs effected.
