[ltp] swapping ultra-bay (slim) batter and dvdrom drive - alarm

[Ram Bhamidipaty]

I have a T40 and normally keep and extra battery in the ultra
bay slot. When I try to switch the battery for the DVD drive
some kind of alarm starts going off and the only way I can 
shut the alarm off is to reboot my machine.

I looked in the BIOS setup section but I did not see
anything that looked right - probably I missed something.

Do I need to run some kind of extra software or is there
a BIOS setting that can control the alarm?

Thanks for any info.
In case it matters I'm running red hat 9.
