Clearly the bios doen't support the function used to implement that
It could be changed to use a differnt bios call that is much more likely
to be supported - ie the read the 18.2 Hz counter.
If there is 'demand' I could do this.

The CF card should support multple sector reads - regardless of the
number of sectors reported as supported in a single command. That
is for a different feature where you can (IIRC) reduce the number of
interrupts by transferring the data in multi-sector busts.
It doesn't affect the ability to read more than one sector in a
normal ATA read command.
You could always try sending the CF card back as 'not working'!
We tried this with some that didn't return a correct 'drive identify'
response (some locked solid, others had a missing field) - they
just came back with a nice new FAT16 filesystem - which we didn't want!
