this looks like a sign that the kernel you're using is configured to try
to use

harddisk DMA right at boot.  That *could* cause problems in rare cases.
SectorIdNotFound looks like a bad sector on the harddisk though.
looks like you can't get into linux at all... try scandisk from windows
on Thorough setting (have to format linux partition as fat32 first).

Promise Ultra100 IDE PDC20265 chip problem

I am attempting to install the new beta release of Red Hat (fisher) on my
home computer. It has an Asus A7V motherboard and a Promise Ultra100 IDE
controller (PDC20265 chip), with two partitions. Windows ME is installed in
the first partition. The second one is where I'm attempting to install Red
Hat.

In previous releases of the Linux kernel, my hard drive was not seen at all.
I could go all the way up to the point in the Red Hat installation where it
wanted to do disk geometry, and then said that I didn't have any mass media
device. Searching through various mail archives lead me to believe the
culprit was the PDC20265 controller chip and the fact that it was too new to
be recognized.

In the new kernel 2.4.0 (and thereby the fisher release of Red Hat), I now
see the error below printed out to the console when booting from the Red Hat
installation floppy. After the error is printed out, my computer hangs. I
apologize in advance if this is not a Linux kernel issue, and appreciate any
help that can be provided.

If you are, in fact, I suggest you contact RedHat.

This is something that windows has been hiding from you.
