LinuxPPC Hard Disk Partition Map Error

Hello:

I recently got my LinuxPPC 2000 CD
in the mail and used thier new xWindows X Linux Installer which includes a handy little app called perldisk.  This will partition your old Mac Hard Disk into whatever I want.  Following the install proceedure in thier PDF Users Guide, I partitioned and installed.  Upon restarting my hard disk was not seen.  I booted into the Linux installer again and when I tried to launch perldisk, I got an error of   "Can't call method "read_partition_map" on an undefined value at /live/live_sbin/perldisk  line 57"  Having 12 years of Mac OS tech experience and a year of NT tech experience, my guess is that during the partition process I screwed up the hard drive's partition table or something.  
The machine is a Power Mac 8600/250 with a Quantum SCSI 4GB Hard disk.  Trying to boot into the mac OS from the original disks returns a bus error and I can't get anywhere else on the machine.

thanks for your help.

Hmmm. Sounds to me that the data on the partions is now gone(if you want to split hairs this is not true, but you'll never be able to access it so its the same thing). Doesn't the mac os have a boot disk? If not you need to make a linux book disk. Not a install disk, but a rescue disk. Then you need to start fdisk. Fdisk is pretty easy to use. However if you need help understanding what it means post and I will help. Also before you start adding and deleting partions, see if you recreate the master boot record. There may be a option for this. Or if fdisk sees any partions make the mac partion bootable. Then you can get back to your data. Otherwise, you will have to make your partions with fdisk.

Thanks.  This helps.  The mac os has a boot disk, but as it starts up it gives me a system error when trying to access the SCSI bus to look at my hard disk.  

But, that aside, I think I'll have to use fdisk.   Could you give me the quick and dirty info on how to use fdisk?
That should fix my problem if I can format it with fdisk.

thanks.

hmmm fdisk is a big program and it explains it's self pretty well. However, it works pretty much the same as the nt fdisk. If you can use that you can use the linux fdisk. Sence the nt fdisk is easier to explain, I'll explian it's functions to you if you don't already know how to use it.

Hi:

I used fdisk and it worked.

I also found out that Mac OS 9 will recongnized linux partitions so I guess I could have used that to boot from too, but thanks for all the help.

Thanks a lot.  I thought I'd have to fork over cash for a new hard disk.

talk later
