Ok, I have checked a lot of BIOS settings and tried the uppermem-trick in grub. All to no avail. Here are the details:
BIOS: S-ATA drives are in "Enhanced" mode, i.e. "Sata and Pata drives are auto-detected and placed in Native IDE Mode". Alternative to this mode is "Compatible" where the drives are auto-detected and put in Legacy Mode. AHCI is disabled. CPU settings (in brackets are the alternatives to the selected variant): Multiprocessor Specification: 1.4 (1.1) Frequency ratio: default (x6, x7, x8) Number of Stop Grant: per Core (single) Intel Virtualization Technology: enabled (disabled) Thermal Management 2: enabled (disabled) C1 enhanced mode: enabled (disabled) No execute mode mem protection: enabled (disabled) Set max Ext CPIUD=3: disabled (enabled) Discrete MTRR allocation: disabled (enabled) Intel EIST support: disabled (enabled) Memory Chipset: Crystal Beach Configure Enable: enabled (disabled) SERR Signal condition: single bit (none, multiple bit, both) Demand Scrub Enable: enabled (disabled) Patrol Scrub Enable: enabled (disabled) 4GB PCI Hole Granularity: 256MB (512MB, 1.0GB) Memory Branch Mode: Interleave (sequential, mirror, single channel 0) Branch 0 Rank Interleave: 4:1 (1:1, 2:1) Branch 0 Rank Sparing: disabled (enabled) Branch 1 Rank Interleave: 4:1 (1:1, 2:1) Branch 1 Rank Sparing: disabled (enabled) Enhanced x8 Detection: enabled (disabled) Force ITK Config Clocking: disabled (enabled) FBDIMM(s) Thermal Throttling: ASUS MemCool Fan (Open Loop, Closed Loop, disabled) Azalia Audio: auto (disabled) ACPI: ACPI Sleep Mode: S1 & S3 (S1, S3) ACPI Version Features: ACPI v2.0 (ACPI v1.0, ACPI v3.0) Headless Mode: disabled (enabled) ACPI EMS Support: disabled (enabled) High Precision Timer: No (yes) When attaching the debugger to the booting process, I can now see that after starting the CPUs the PCI slots are initialised. Until then there's no error message. However, after the last line that is still visible about some PCIe slot (no error message, some debug info) it starts to scroll extremely fast, about one screen worth of debug output, before the whole system goes into the "crash mode", i.e. screen is switched off, only a power cycle revives the computer. I have changed the BIOS settings for PCI to reset ESCD data, which has been successfully done by the BIOS, but it didn't help my problem. Are we now at the graphics card as the culprit? (Gainward nVidia 9400GT) This is the only PCIe-card (actually the only extension card) in my computer. I'm more and more puzzled... Again, thanks in advance for any help! -- This message posted from opensolaris.org
