To more explicitly answer the original question of whether
an Ultra ATA  drive would work on an EIDE controller;

Yes an Ultra ATA drive will work with an standard EIDE (non ultra ATA)
controller, it just won't make use of the Ultra ATA capabilities.
It will mount using standard mode 4 tranfer.
And I would expect that most users would never notice the difference
since Mode 4 transfer rate is well above the sustained
transfer rates of standard drives.

The only motherboards at present that have Ultra ATA capabilities
are those using the Triton TX chipset.
