Dell Optiplex GX620

I have gotten this working in RC4 using the 2-28-08 ACPI.psd. It requires /FS /APIC /CD /SAP:0x20 /EIS to boot. Otherwise it stops at a line that says it is initializing devices/events/objects. APIC works providing high irqs and hypertreading works using 104a SMP Kernel. The problem at that point was very slow video performance using SNAP with with an ATI Radeon X600 Series card. I experimented further and determined that using SAP:0x25 fixed the video problem.

1) Disable hypertreading, it is not stable

2) try boot without SAP switch.

Dell computer -> try use /FS + SMP kernel

IF no /SMP switch then /APIC is not needed

I am attaching several log files created using different switches. No switches won't boot PSD=ACPI.PSD /FS /SMP /APIC /SAP:0X20 /CD /EIS (ACPI.log) PSD=ACPI.PSD /SMP /APIC /SAP:0X20 /CD (acpiapiccd.log) This one works the best performance wise. PSD=ACPI.PSD /SAP:0X20 (acpisiponly.log) PSD=ACPI.PSD /SMP /PIC /SAP:0X20 (acpismppic.log) PSD=ACPI.PSD /SMP /APIC /SAP:0X20 /CD /EIS (acpinofs.log)

The machine is single processor with hyperthreading.

SNAP don't work right with SMP. I see your log. You don't need in /FS, you don't need in /EIS. Can you boot without /SAP:0x20 ?

[Chuck McKinnis]

An additional note shut down doesn't work properly. Using Xshutdown it will turn off the computer but it immediately comes back on. If I set it the use ACPI for power off the reboot caused by the restart fails (hangs with the logo showing) If I use APM the reboot caused by the power off works.

If PowerOff?.exe work right - problem outside acpi

[Chuck McKinnis]

Poweroff does the same thing. The power goes off but comes back on 3-4 seconds later.

[Chuck McKinnis]

Check your BIOS settings carefully. My ThinkCentre? has some very odd options that cause it to come back on after a power off.

Hi

Sorry for the long delay in responding. I can confirm that /FS and /EIS are not needed. However without /SAP:0x20 it hangs early in the boot sequence. I will try RC 5 this weekend and report back. I have hyper threading turned off. I only turned it on for testing. I don't know what is causing the problem with the restart. It doesn't restart if the power is cut (power outage) even if it is very brief.

I installed RC5 it works with the default settings /FS /PIC. It also works with the recommended settings (adds /SMP) and the SMP kernel if hyperthreading is off. It works with it on but is very slow. It does hang with /APIC when the uniaudio 1.1.4RC4 driver loads. I consider this issue resolved. Thanks

Version (RC6a) 3.14 fails to boot from CD. The problem may not be the same the SAP:0x20 switch doesn't fix it. If ACPI 3.14 is installed to hard drive it will boot if No hardware detection is set either in the the hardware object or at boot time using ALT+F1 F6 (I think). The point of failure using the debug driver is shown in the attached picture. It fails silently.

Pasha reminds:

it's necessary use /FS switch, do you use it?
