s/machine/workstation/
I'm pretty sure all 64-bit capable servers properly handle
PDC calls in wide mode. PAT PDC supports a few calls in
narrow mode (for boot loader) but the rest must be in wide mode.
Note that IODC generally requires narrow mode.
(Superdome IODC is different - but I don't recall exactly how).
BTW, I prefer Matthew's rewrite over the Thomas' proposal.
No offense intended thomas - thanks for submitting the original.
