** IMPORTANT **
** If you have a 1533 or 1543C on the board and you get
** "ali15x3.o: Error: Can't detect ali15x3!"
** then run lspci.
** If you see the 1533 and 5229 devices but NOT the 7101 device,
** then you MUST enable ACPI, the PMU, SMB, or something similar
** in the BIOS. If you can't figure out how to enable the
** 7101 device in the BIOS, you have to upgrade your BIOS.
** The driver won't work if it can't find the 7101 device.
The SMB controller is part of the 7101 device, which is an
ACPI-compliant Power Management Unit (PMU).
