I've been able to fix the DSDT completely for this laptop (0 errs, 0 warn, 0 rem, 883 opt), and compiled it with iasl 20050309 (the latest ver gave me a lot of missing Resource String errs for some reason). I will be posting it to the dsdt db shortly. Thanks a lot for the hints. One note that I still had trouble booting even with a fixed DSDT and had to use 'acpi=3Dnoirq', or if I wanted to use the 'noapic' setting, I had to add 'irqpoll' also or else peripherals like the nic would refuse to work properly. My guess is that this laptop still has firmware issues with irq. In the mean time, from what I can tell, it detects *everything* (APIC LAPIC HPET PCI0 ELCR EC0 ACAD BAT1 PWRF LID PWRB SLPB CPU0 USB* RP0* LANC AZAL GFX0 C* S* THRM). Anyway, back to more laptop hacking. This 3lb laptop rocks once acpi starts working its magic. ^_^ bao On 8/11/05, Thomas Renninger wrote: > Bao Tran wrote: > > First off, just wanted to say thanks for everything so far. > > > > Secondly, I just got an Acer Travelmate 3002wtci, and the first thing > > I did was rip out the hard drive and tried to put linux on it.
