Current report is as follows...Changing the Fireball from id 1 to 0 made Mac OS boot from the device so I can get into BootX. I tried to rewrite the partition table with fdisk again, and this time got:
Kernel panic: Exception in kernel pc c0205a90 signal 4 Rebooting in 180 secondsHas this problem got anything to do with the disagreement between the kernel and fdisk over the number of blocks on the drive? The kernel (on startup) always reports that the drive has one more block than fdisk does. I decided to believe the lower count... I will try again with the higher, but would really appreciate some help here (I'm a stuck newbie!)
No joke, I have been trying for 3 months to get Debian on my Mac...When I keep the Apple partition map and driver partitions I get SCSI errors all the time which end up eating my system (as stuff goes to lost+found).
Without, I cannot even write the partition table.The drive is ok under mac OS. I have checked for errors a million and one times.
Bruce McIntyre wrote:I am continuing to have frustration with my internal hard disk (7300, Quantum Fireball 2.1) I decided to this time mash Apple OS altogether, and so gave mac-fdisk the 'i' command to write a new patition map. I was suspecting that the apple patch and driver 43 patitions were causing the scsi error 80000000 that I was getting with my previous installs. The initialisation went fine (fdisk prompts you to enter the block size of the disk, which I got from first giving it the 'p' command---it returns a size 1 block less than that given by dmesg). I wrote in some partitions. 32M Root, 32M swap, 100M var, 500M home and the rest usr. when I gave mac-fdisk the 'w' command (to write the new patition table) it freaked out and gave me something like (copied by hand from screen):Kernel access of bad area pc c0206808 lr c0205a70 address 4 task mac-fdisk 44it then panicked and all consoles froze as it attempted reboot (which never eventuated). Now I cannot reinstall a working Mac system on the disk to start the debian tranistion--- it formats ok with the apple Drive Setup utillity, but refuses to make the disk bootable with the startup disk control panel (system writes to it ok in the install program). while the startup control panel indicates it is the boot disk, at boot i dont get anything, only grey... not even the disk icon. to boot again from cd, i have to erase the pram, and then reboot with c and d held down. after a minute or two of indecision it boots, and mounts the drive fine, with the system on it and still indicating that it is the boot disk. The drive is on the mesh bus at id 1. (I have been trying different ids to get debian without scsi errors to no avail) Is my computer cursed?Probably not.I have a 7300 and it's a good machine, but it's hard drive is starting to go bad on one sector. I'm going to have to get a new drive. You might try that too.Would love to but am starving musician! (I have checked out the sectors with 3 different progs: they _seem_ fine)Here's some other things to try: Remove and reinstall the memory modules and cpu boardthe potential for me breaking it worse is huge here...Unplug each connector and reinstall them; like the scsi cables, power cables, etc)Have done with scsi--- strange thing is that the drive is always found and usable when booting from cd.... I don't think it's a simple intermittent problem (contradiction in terms?!) perhaps open firmware is not looking on mace at id 1 for boot (is that id reserved for external bus or somthing wierd like that ? I'm going to put the drive back on 0 (time to get screwdriver) and i'll report on progress again.Check the power output of the power supply with a voltage meter (buy a power extender and cut and strip the cable to attach the meter clips) Sorry, don't know which wires to check... Kicking it a couple times might help... ;)didn't someone make a cushion in the shape of a mac plus for that purpose once :-)Hope this helps, Mike-- To UNSUBSCRIBE, email to debian-powerpc-request@lists.debian.org with a subject of "unsubscribe".
