[Chuck McKinnis]

Acer Aspire 5550.

Trap is the same as ticket 143. Traps when ACPI.PSD is loaded (ACPI 3.04)

Could not fetch data with iasl.exe

Included in acer2.zip:

• output of scanner.exe (version Rudiger posted on the 1st November 2007 to acpi-dev mailing list)

• also output of acpica$ log. (booted ACPI with /SAP:0x20 switch)

• output of pci.exe -d

My question is

I asked Eugene why the SAP switch was introduced in ACPI. He said this was done because many systems don't have a PCI bios. Could you explain this a bit more Pasha what Eugene means by this ? Since these same systems will boot without ACPI. So they should have a PCI bios otherwhise the system would not boot (Does OS2LDR not need a PCI bios ?)

This machine is from Joerg Skottke

Users of Acer notebooks should search for modified ACPI tables on Linux sites.
