A little more info would help. What OS, is this a clean install? Has this worked in the past?
This unit is sold with many Dell Laptops. There's plenty of questions and answers about this drive and same issue on Dells forum. Dell reps say pretty much the same as mentioned here.
The thing should boot with a bootable CD.
Should be able to use allmost any 4X ATAPI CD.
Win98 boot disk with CD support should work.
On some of the Dell systems there is a driver for the Bay Manager. It allows for hot swapping devices. There's a icon that's by the time simular to a PCMIA card device. Once selected you can choose to remove or insert the different drives.
If I remember correctly the drive doesn't work on the floppy cable so that's not related.
Here is a link to Dell's forum about this drive and part number.
