My new CPU is an Athlon 64 X2 4600+ (socket AM2). My motherboard is an ASRock AM2NF6G-VSTA. I had to upgrade the BIOS to support the new processor, so I upgraded to the latest available version: 2.30. I have eCS 1.2MR installed and I regularly apply updates from eCSMT. Previously I had a Sempron 3200+, so I had the UNI kernel. I installed the SMP kernel and related DLLs, then tried to enable SMP in ACPI. Here are my results: 1) PC works as before in 1 CPU mode (PSD=ACPI.PSD /CD), just faster. 2) If I enable SMP but do NOT enable APIC (PSD=ACPI.PSD /SMP /CD) I can boot to command line without problems. When I try to start PM, I get a trap D in the kernel before reaching the desktop. I tried several combinations of switches *without* /APIC with the same results. 3) If I enable SMP _and_ enable APIC (PSD=ACPI.PSD /SMP /APIC /!NOD /ALS) the computer hangs during the boot process. I tried several combinations of switches *with* /APIC with the same results. Note that on first boot with /APIC I could not boot because eCS said it was unable to operate my disks. I have SCSI disks, and I boot off an SCSI disk. Then I read how to remap high IRQs to the original low IRQs, and after doing it eCS was able to boot, but then it hung. I noticed that HDA audio gets an high IRQ too, so I tried to remap it too, but this time it didn't work. Maybe it is because I try to remap to IRQ 11 which is already used by SCSI... but when in PIC mode they share that IRQ without problems. That's because you find three remapped IRQs in the acpi.cfg file. LOGS: ----- You find attached logs that I collected for situation number (2). I could not collect logs from AcpiManager because that would have started PM, which in turn would have caused the trap. Image 148 refers to the kernel trap that occurs few seconds after when I start PM. Image 149 refers to the hang that I get in situation number (3). The fans are always quite loud when in SMP mode (with or without /APIC). Hope this helps! I really want to use my new dual core processor! ;-) Bye Cris (criguada at gmail dot com) " defect closed blocker Release version 3.10 ACPI PSD 3.09 fixed
