 YES, both disks have LBA support, and indicate a Block Mode 
 of 16, PIO Mode of Mode 4 and Ultra DMA Mode of Mode 5 - whatever those
 mean.

I don't think the BIOS is confused - I think this information 
is just not stored there. There is a statement in the BIOS 
screen that details the Drives: "The actual performance of the 
Drive is Dependant upon the Operating System and IDE Drivers."

At the same time ananconda appears to have found both 
driver. Is there anywhere in the various configuration and 
log files that what it found might be listed?

This is a retyped copy of grub.conf - since I am only able to 
get at it via 'linux rescue' and I am working from an XP 
machine, to be able to handle email.

If the above does not help I will spend sometime there 
tomorrow ... Any suggestions about GRUB places?
 
Thank you for taking time with this...
