[Pete Peters]

Eric,

Info about Pdisk and using it can be found at the following links;

You can download Pdisk from;

Are we having fun yet?


Pete

Now my next question is:

How do I get to pdisk? I assume I have to be in YDL to run the app, but I
doubt that I will be allowed to format the boot partition.

I have the YDL 2.1 and 2.2 Install CDs and tried booting the 2.1 CD but it
wouldn't let me (failed with some error & said it would restart in 180
seconds (& I wasn't able to command-control-power to restart for the first
time ever (B&W G3, ADB keyboard)... I thought com-ctrl-pwr was a hardware
thing and didn't think software could over-ride it)).

I've mangled the Linux partition (1536 MB) with the installer (trying to
trick it into formatting me one big boot partition). Should I re-install YDL
and try deleting the partition that way (using your pdisk instructions)?

Thanks for all your help, Eric.
