Hi there, I know that probably many machines (espeacially old ones, like mine) fail to work with ACPI. Nevertheless I would be happy to play with/test it, or at least understand what happens, if I'll be able to make it move. Info on the "patient": Happily running: %uname -a FreeBSD host.mynet.edu 5.2-CURRENT FreeBSD 5.2-CURRENT #1: Tue Dec 16 12:02:30 EST 2003 user_at_host.mynet.edu:/usr/obj/usr/src/sys/GENERIC i386 Previously: FreeBSD host.mynet.edu 5.2-BETA FreeBSD 5.2-BETA #0: Sat Nov 29 21:12:25 EST 2003 user_at_host.mynet.edu:/usr/obj/usr/src/sys/NEWBBU20031128 i386 Motherboard: Intel AL440LX (Atlanta) inside a Gateway 2000 GP6-333 Bios Phoenix (last, just installed): 4A4LL0X0.15A.0023.P18, release (by Gateway) 6/28/2001 Dmesg errors: Pentium Pro MTRR support enabled ACPI-0159: *** Error: AcpiLoadTables: Could not get RSDP, AE_NO_ACPI_TABLES ACPI-0213: *** Error: AcpiLoadTables: Could not load tables: AE_NO_ACPI_TABLES ACPI: table load failed: AE_NO_ACPI_TABLES The same error happens with static linkage of acpi in 5.2Beta, or as module in 5.2 Current (as 12/15). Tried: host# sysctl machdep.acpi_root machdep.acpi_root: 0 host# acpiconf -h acpiconf: /dev/acpi: No such file or directory (of course :)) Seems that function AcpiTbFindRsdp/tbxfroot.c#L501 fails. As the search seemed to be done in: <quote> NOTE: The RSDP must be either in the first 1K of the Extended 495 * BIOS Data Area or between E0000 and FFFFF (ACPI 1.0 section 496 * 5.2.2; assertion #421). <quote> I tried to search for ID "RSD PTR" in /dev/mem Some (irrelevant ?) positions till I stopped the search are listed at the end of the email. What can I do more? I activated also the ACPI_DEBUG option but it seems to produce no more info as acpi fails at the beggining... I no that the ACPI work is undergoing and this is a minor issue, but if I can track/look/search/try something, anybody, just give me some pointers where I should focus my attention. Thank you for any suggestions, opinions.. I will gladly provide more information on this if needed. Just tell me what to squeeze as I am out of inspiration. /Dorin.
