145	Again trap with ACER laptop (as ticket 143)	Chuck McKinnis	pasha	"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
