Hey, I just did that dual master trick yesterday too! Trashed my
development disk and everything...note that having two "regular"
hard drives as masters will stop the boot process in the BIOS,
not so with CF...wonder why...
Anyhow, I'm getting file system errors after I format and load
the CF...not sure if there are bad blocks or what is happening,
but if I run fsck:
/sbin/fsck.ext2 /dev/hdb1
I get all kinds of errors (after the files are copied). It will
boot, but generally stops somewhere along the line with a read
error, kernel panic, whatever (these seem to be random)....
This happens even if the device is set as a master (/dev/hdc1)
Something about these devices is different than a normal flash
device - I have no problems using a flash disk, Disk-On-Module
as an IDE device.
Still hacking on it....
Later,
Ralph
