A Rev. 1 ROM in a Rev. C mobo does not have any problems at all. 
Therefore the drive corruption issue, if it is indeed an issue, is most 
likely associated with the Rev. A mobo, not the Rev. 1 ROM.

Note that valid (factory) combinations of mobos and ROMs are: Rev. 1A, 
Rev. 2B, and Rev. 3C.

Note also that functional (user implemented) combinations include (but 
are not necessarily limited to) Rev. 1B, Rev. 1C, and Rev. 3A.

Rev. 2 mobos (with Rev. B ROMs) are almost exclusively asociated with 
late 266 MHz DTs, not with MTs. 300 MHz and faster were, in my 
experience, always Rev. 3 mobos. And, there were no 300 MHz DTs, due to 
inadequate cooling inherent in the DT case design.

Change out that 45 CFM fan in your DT for a 65 CFM fan (available from 
Digi-Key and others) and the cooling problem is somewhat alleviated.

Special cables are required for a squeaky-clean, reliable installation.

Contact me off-List for custom made DT and MT cables, which support two 
HDs on Bus 0, if interested. Designed and tested at UATA/33 (33 MB/sec), 
but employed at 16.67 MB/sec in a DT/MT, as that is a limitation of the 
Beige mobo.

True, but the upward/downward compatibility is good.

The supplied CD-ROMs and ZIPs are indeed EIDE. The supplied HDs are ATA.

The Beige's Bus 0 and Bus 1 are identical (unlike its successor machines, 
where the Bus 0 was ATA while the Bus 1 was EIDE).

No problem with UATA/33, UATA/66, UATA/100 or UATA/133 drives on a Beige, 
although a Beige only supports 32-bit LBA, so you will be limited to 137 
GB (120 GB, for all practical purposes).

Works imprefectly or perfectly, as a function of processor speed.

350 MHz is about the minimum, but 300 MHz may be fine for some movies.

(I have gotten it to work on a 7300/200 ... yes, a 200 MHz 604e processor 
... but it is not pretty ... 300 to 350 MHz on a 7300 is fine).

533 MHz is just about as perfect as it gets.

A Radeon 7000 (Mac Edition, or a PC Edition which has been FLASHed) is 
required unless you have the "unobtabium" DVD decoder transition card.

The above on OS 9.1 or 9.2.1.
