> 137,000 MB is the limit for an early QS.

Oops ... the limit is 131,072 MB, computed as follows: 128 megabytes
(where a "megabyte" is really 1024-based, and not 1000-based) = 131,072
MB.

The problem is: the early QSes support only a 24-bit LBA size, whereas
late QSes support a 48-bit LBA. The difference is in the ROM, so a hybrid
machine, say, an early QS with a late QS motherboard, can be treated as a
late QS.

Application of the O.F. hack forces the early QS to use 48-bit LBAs, hence
large drives will work in those cases.

I HIGHLY RECOMMEND partitioning your large drives with 128 MB as the first
partition, and the entire remainder of the drive as a second partition.

In this way, your drive will be compatible with old or new QSes, with or
without the O.F. hack, and the only downside is the second partition will
not be seen if LBA48 is not being used.

Heck, you may even use such a large drive as your boot drive.
