Got a question on configuring a second harddisk on a system..
My system : Asus P2L97 mainboard -> 2 ide slots udma/33, WD Caviar 4,3 Gb HD (u-ATA/33 i think), A-open 36x CD player ATAPI (u-dma/33), adaptec scsi controller, plextor scsi writer, win98
The 2nd HD is a WD Caviar 20,4 Gb Ultra ATA/66 (retail version) with IDE cable.

Q1a: can a uata/33 and uata/66 work together on a system?
Q1b: does the Asus P2L97 that supports U-DMA/33, also supports U-ata/66??
Or can i just plug it so that the speed is maximized to 33...

in the manual i read the packaged IDE cable must be connected to BOTH HDs, the grey on the master and the black end on the slave...

Situation now is that the 4,3 Gb HD is the primary master, the cd player the primary slave with i think ide/33 cable (40 pin?).
Secondary slot (i guess secondary m/s) is free: just plug in the NEW cable and NEW HDD to that 2nd ide slot (both uata/66) or replace new HDD to primary slave and cd player to secondary (master or slave, then???)

do i need to change jumpers on cd player then (although Aopen's CD installguide recommends not to change them)?

Q2: does it matter how to put the jumpers of the HDs when primary or secondary? do i need to follow the guidelines (master and slave settings on dual drive system as shown in installguide)
