Tried sda8, sdb8, sdc8,and disk/by-label/11.2  All with the same result.

No, I have 3. Two ide (80GB & 150GB) designated sda and sdb in that order, and 
one sata (250GB) designated sdc. The 11.2 is ond sdc8.

Yes an unpopulated USB card reader

Yes, every Linux partition on all drives is designated /dev/disk/by-label and 
they are all reflected that way in fstab.

The two PATA ports are hda, hdb (sda, sdb) There are only two on this new 
board. The rest are all SATA. (Had to buy a new SATA DVD writer)

Well, something happens.And I can't explain it. If I go into the rescue system 
and choose "boot installed system" for 11.2 it is shown as sda8. It boots 
11.2 perfectly. Why it shows sda8 instead of sdc8 I have no idea. Very 
illogical. Remember now, I tried to boot normally as sda8 and got that stupid 
message about finding it. The partitioner, fdisk, and Parted Magic all show 
the disk layout correctly.

This is crazy. Why should replacing the MB have anything to do with booting?
That is all HD stuff except for the bios. And that all seems to be correct. 
And why does the install/rescue system mis-identify tue disks in a seemingly 
random order?
