Not sure how dumb a question this is, but I'm gonna risk embarrassing myself, anyway. 
I have a Pioneer DVD-ROM, which according to the BIOS and Windows Device Manager runs in DMA Mode 2. Also, I have an Acer CD-RW, which when I boot up supposedly runs in PIO Mode 4 (I have selected it to run DMA Mode 2 in the BIOS), but Windows Device Manager says it's running in DMA Mode 2. Both these devices are set to Master on IDE 1 and IDE 2, respectively. Last but not least, I've got an Iomega Zip250 IDE, which is said by the BIOS and Windows Deivce Manager to be running in PIO Mode 4. This I am running as slave on IDE 2, as suggested by the manual/installation instructions that came with the drive.
Am I correct in assuming the following correct about PIO and DMA modes:
PIO Mode 4 = 16,6Mb/s
DMA Mode 2 = 33,3Mb/s
??
My questions are: Is there a way to get the Iomega Zip250 to run in DMA Mode 2, and if not, would I be better off running it as Master on a seperate IDE cable, and set the two CD-RW/DVD drives to Master/Slave? I've heard several people say that if you connect a PIO Mode device and a DMA Mode 2 device on the same cable, both devices automatically run in PIO Mode 4. Is this true?
Also, despite the fact that my CD-RW appears to run in DMA Mode 2, I don't like how the BIOS reports that it's running in PIO Mode 4. (I get this information when booting -- the screen that briefly shows how many harddrives, memory, etc. is installed?) Is there a way I can change this? And would it be possible to change the name the device is listed as? It only reads ATAPI 12/8/32, and I would like it to say Acer 1208a, or something. I know this is the least of my worries, but...
