A friend has a Compaq 48625SX all-in-one model(Presario Net/25S) that came
with a 100MB IDE hard drive.
She wants to replace the drive with a 540MB, but cannot get the system to
take it. When she tries to boot up, after installing and manually changing
the bios for the 540, she gets a "controller failure" error message. She
tried another 540 drive with the same result. Both drives are good.
Putting the original drive back, the thing works normally again. Your help
appreciated,
