512 MB is an IDE specification limit. The newer IDE drives get around it by
using Western Digital's enhanced IDE specification, which uses the BIOS.
32-bit disk access bypasses the BIOS so it won't work. This is also why the
TP750 will need a flash BIOS upgrade before it can use the larger drives.
(The 360 and 755 already have the updated BIOS)
If you really really want 32-bit disk access, you should be able to
partition your disk as 512 MB (waste the remaining 28 MB).
When did Micro Machines get the 540 MB drives? They didn't have any a month
ago.
