Title: Problem booting from compact flash on Lombard
Post by: rshaw on March 25, 2017, 03:32:50 AM
Hi, I have a Lombard 400Mhz G3 running OS 9.2.2, and am trying
to boot from a CF card in the PCMCIA slot.  There is now a 32 GB
SanDisk UDMA7 card in the slot, via an adapter, and I could format it,
and it shows up on the desktop.  I copied over the system folder and
the finder, but I can't boot from it, the relevant entry is greyed out in
the Startup Disk control panel.  I did a few incantations to "bless" the
system folder, and zapped the pram, no change.

Do I need to boot from a CD to load a system on the CF card?
Is there something I'm missing?  Thanks for any suggestions!

You can only boot from the internal PATA slot or SCSI. You might be able to boot using some Open Firmware trickery, just like you can boot newer PowerPC Macs via USB using Open Firmware, but not "out of the Box" so to say.

Thanks!  Though that's annoying, how do I make a bootable backup?
Do I have to find a SCSI disk and adapter?  Or can I clone the internal disk
using the card slot or USB?

I'd be interested in pointers to "open firmware trickery", though it sounds
like a time sink, and a good way to make a disk unreadable...

Thanks again,
rob

Just a note, I looked into booting from CF in open firmware, looks like it can't be done on a Lombard.
One can get into open firmware, and then go
0 > dev /pci/cardbus@13
0 > words
and get a list of a lot of commands for the PCMCIA slot, but the needed command is "load",
it's not there, also not available for the USB ports, so can't boot from a USB key either.
If there's a way around this, using available commands, I'd be curious!

So the backup strategy is to copy all files to the CF card (which runs well), and if the disk goes bad,
install a new one, boot from CD, then copy files back onto the new disk.

Thanks!
