Hi,
My boss just put a new server in our colo. It has a Tyan Thunder K8SR
motherboard with 2 Opterons. When I boot an SMP kernel, dmesg.boot
includes the following:
CPU: AMD Opteron(tm) Processor 246 (1991.88-MHz K8-class CPU)
Origin =3D "AuthenticAMD" Id =3D 0xf58 Stepping =3D 8
Features=3D0x78bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE=
,MCA,CM
OV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2>
AMD Features=3D0xe0500800<SYSCALL,NX,MMX+,LM,3DNow+,3DNow>
real memory =3D 2147483648 (2048 MB)
avail memory =3D 2061676544 (1966 MB)
ACPI-0159: *** Error: AcpiLoadTables: Could not get RSDP, AE_NO_ACPI_TA=
BLES
ACPI-0213: *** Error: AcpiLoadTables: Could not load tables: AE_NO_ACPI=
_TABL
ES
ACPI: table load failed: AE_NO_ACPI_TABLES
My searches have indicated that the most prevalent causes of this are
ACPI not being enabled or an out-of-date BIOS. The motherboard manual
indicates that ACPI is enabled by default, so should our next step be
just to update the BIOS and hope for the best?
Is there a clever way to determine our BIOS version without physically
accessing the server?
TIA!
