Will an Ultra ATA HD, such as the Quantum 4.3gig Fireball work if I
was to connect it to an EIDE card (Promise EIDE4030+).

Thanks.

Ultra ATA requires both a hard drive capable of it (only the Fireball ST
series, not the Fireball TM series from Quantum) _and_ an Ultra DMA
controller (at present only available built in to a few new
motherboards.  EIDE controllers just won't do it.

Cheers

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.

Agreed on all but the chipsets that support it. The Apollo VP-3 (as on the
Rhino-12 motherboard) also has support for this standard, not just the TX.
