>From the looks of things, you have one drive as master and one drive
as slave on the first IDE interface, no hard drives on the second
IDE interface, and one drive as master on the third IDE interface.
If the BIOS is set to autodetect drives on the second IDE interface,
it is going to generate the messages you are getting. It is not an
error, or the BIOS not seeing the drive. It is just the BIOS telling
you that it did not find any hard drive when it checked. You could
probably speed up system boot by disabling the check in the BIOS.
You could also set the drive types for the other drives, so the BIOS
does not have to check each time it boots. This is up to you. You
get slightly faster boots, but you will have to go into the BIOS and
change things if you change drives.
