Line 4:
To find the RSDT you need first to locate and check the [[RSDP]], then use the RsdtPointer for ACPI Version < 2.0 an XsdtPointer for any other case.
The ACPI standards state that an OS that complies with ACPI version 2.0 or later should use the [[XSDT]] instead of the RSDT, however I personally doubt that there is a difference on 80x86 computers. AFAIK the XSDT itself was introduced for Itanium's (IA64) and other 64 bit computers where it's likely that the BIOS (and ACPI tables) are above 4 GB. On 80x86 it's likely that the RSDT and the XSDT both point to the same tables below 4 GB for compatibility reasons (it doesn't make sense to have 2 versions of the same tables) -- Brendan.
==Validating the RSDT==
Line 109:
* "SRAT": System Resource Affinity Table (SRAT)
* "SSDT": Secondary System Description Table ([[SSDT]])
* "XSDT": Extended System Description Table ([[XSDT]]; 64-bit version of the RSDT)
=== Reserved by ACPI ===
