RE: ACPI:system description tables not found.

[David Christensen]

Stephen,

Your BIOS isn't reporting any ACPI capability.  If it were you would have at
least two more entries in the e820 output that say ACPI NVS and ACPI
Reclaim.  Have you been able to install a MS OS and have it recognize ACPI?
Are there any other BIOS settings that might be related (what about a PnP OS
setting or something under Power Management)?  You might also check for any
BIOS updates available from the motherboard manufacturer.

The BIOS setup option for ACPI is enabled.
