211	Acer Aspire 4720, ACPI crashes	Doug Bissett	David Azarewicz	"From: Doug Bissett 

eComStation 2.0 RC4 installer


Message 1:
I have a new Acer Aspire 4720 laptop. The general description is:
Intel core duo T5450
2 GiB memory
250 GiB HDD
other things, that seem to be irrelevant, at the moment.

If I leave ACPI enabled, I get a crash in ACPI. See the photo AcerTrap.jpg for the details. If I disable ACPI, and edit CONFIG.SYS to add a fifth USB controller (see other report), I can get booted to the GUI.



Message 2:

Okay, I got this to (partly) work. It seems that this laptop has an invalid ACPI table, but I got the system booted, in 2 processor mode, by using the line:
PSD=ACPI.PSD /SMP /PIC /EIS /FS /SAP:0x20
I am not sure if /FS is actually needed. The ACPI wizard told me to use
PSD=ACPI.PSD /SMP /APIC
which didn't work. /APIC also doesn't work.

I still get a hang, if either of the NICS is enabled, but that could be because of the invalid table. More to be done, when I find a few minutes.
