Nope. Not in any of .configs for all 3 2.6.15 kernels I have compiled so far. > If so, then you're good. If not...

As soon as I say that /dev/ubda exists, I realize this AMD64 image does not have a ubda device. So I created one, using "mknod /dev/ubda b 98 0". /etc/fstab was already setup to point to ubda. But it still gives the same error when I try to boot it. :-( Thanks, Jacob -- GnuPG Key: 1024D/16377135 Random .signature #17: Fatal Error: Found MS-Windows System -> Repartitioning Disk for Linux...
