would a UDMA/33 mb support an ata100 harddrive?

here's the issue, got a cheap aopen MX3L board with on board IDE (UDMA/33)

it's time to upgrade with a bigger drive... i'm thinking about getting a 40gig 5400rpm ata100 drive for it. because if i decide to upgrade again later, i can use it on a better motherboard.

so the question is, would the drive work on the motherboard? (with degraded performance of course)

anyone?
 
nevermind, found the answer myself....

on maxtor's website... the short answer is yes....

with expected degraded performance....
 
That's not all there's to that. Some older BIOS will attempt to program the IDE bus to the drive's best UDMA mode, forgetting that the mainboard's IDE channel can't do that.

For those cases, you need to use Maxtor's drive configuration utility program to make the drive pretend it's an UDMA33 device. (This is reversible.)

Then, if that old board has an Award BIOS before mid-1999, then it might hang at boot with drives larger than 32 GBytes, with no way around it other than jumpering the drive to "32 GB cutoff".
