Powerbook 5300c & booting from CF cards (PCMCIA & as IDE drive)
I'm trying to "upgrade" my vintage PB 5300c and replace the internal noisy slow HD to using CF cards via the IDE-CF card adaptors.
in theory, this should be pretty easy.. format the CF card as HFS, install OS (trying 8.1), connect everything and reboot.
however, I'm having severe difficulties. First, I couldn't get the 5300c to boot off the CF card via the PC card slot at all (ejects the CF card not finding any OS on it). This, I managed to figure out that using HFS+ was a bad idea. So I reformatted the CF card to HFS (standard), and then re-installed 8.1. At least this time it would recognize a system folder and try to boot.. but soon after the MacOS splash screen it crashes stating "bus error". I managed to get it to reboot once while holding the shift key, but only that once.
I've tried installing the CF card to the IDE drive chain, and managed to get it boot in OS8.6, but it's kinda slow.. so I would really like to boot into 8.1...
But either way, I need to make sure I can boot this thing via pc slot before I put it back into the IDE drive bay. so under HFS, I have tried installing a fresh copy of OS8.6, 7.6, 8.1 to no avail. it still boots fine via the internal hard drive, or using SCSI external. I haven't tried putting the CF card back onto IDE bay yet.
What is wrong? is there something wrong with the motherboard/logic board that is preventing it from booting from CF? I'm starting to think there is something more sinister than just a plain-vanilla "bad OS installation".
All installation is done on the 5300c, either through an install disk image on the CF, or the internal HD, or "drag-drop" a known working OS onto the CF.
I have at my disposal, my trusty Al-PB G4 running Leopard (kinda useless other than downloading stuff from the net and loading on to CF to get it on the PBs), PB G3 Lombarde (somehwat useful, although it won't work under 8.1, so trying the installation on that machine is useless). I also do have another 5300c with a bad power connector (the solder ripped off) so i do have some spare parts to swap if needed...
any ideas what to do? I guess I can try to install OS7.5 (painful...) instead of 7.6 and see if that works... I'm totally baffled, and I'm starting to get a bit discouraged here...
