Re[2]: help-HD swap

     Hey,  I'll check the site to verify what you are saying but it defies 
     my current reality.  EIDE is a different standard with different pin 
     outs.  I have freely been swapping hard drives between laptops for 
     Years and IDE drives have been easily swapable.  The 540 and 810 
     drives from IBM are IDE not EIDE.  It is conceivable that a BIOS 
     upgrade was needed to upgrade but this does not make IDE into EIDE.
     
     IBM started using EIDE with the 760 series and with the 1.2 GB drives. 
     On these machines you can not use the old hard disks in the standard 
     bay!...Someone on this list posted that one can get the old disks in 
     the Ultra Bay.  I am anxious to try this but earlier discussions with 
     IBM tech's indicated that this couldn't be done.  We will see!
     
     If the drive you purchased is IDE (Likely) then you may indeed need a 
     bios upgrade to get it to work but if the drive is EIDE (Unlikely) I 
     would send it back and get an IDE drive.

540 is an EIDE drive.  You may need to flash upgrade your BIOS.  When 
the 750s first came out, only 170 and 340 MB drives were available. 
When the 755's and 540/810 MB EIDE drives became available, IBM put 
out a BIOS update for the 750s so they could use the EIDE drives.
You can get the latest BIOS from ftp.pcco.ibm.com in /pub/mobiles.
