Enable 32 Bit transfer in BIOS IDE setting?

In a P4C800E-Deluxe...
The guide does not give a default. Will the motherboard revert to 16 bit if
you don't?

I set all mine to 32 Bit transfers. I notice a measurable difference
in boot time (several seconds) when loading XP if my boot drive (WD74g
Raptor SATA) does not have 32 bit transfers enabled. Graphically,
when XP loads and I watch the little loading bar under the logo, with
32 bit enabled it only makes 2 passes and then launches to the
desktop, with 32 bit disabled, it makes 4 passes. Once it is into the
operating system I suspect that it does not make any difference as XP
handles disk management by itself.

My WD Raptor SATA 74GB shows in the BIOS as supporting both MWDMA 2 and UDMA
5; I set it at the latter, is that correct?

Also, should I set my IDE Zip drive to 32-bit transfers?

How can this be, if the drive is SATA? Anyways, UDMA5 sounds much more
reasonable than mwDMA2.
