5.5.2.26 Segment Base/Limit MSRs
The segment base/limit MSRs provide access to the segment limit and segment base parts of a segment register. The limit
value is the true limit; it does not need to be altered based on the limit granularity bit. The contents of segment registers
should be accessed using MOV or SVDC/RSDC.
ES Segment Base/Limit MSR (ES_BASE_MSR)
CS Segment Base/Limit MSR (CS_BASE_MSR)
SS Segment Base/Limit MSR (SS_BASE_MSR)
DS Segment Base/Limit MSR (DS_BASE_MSR)
FS Segment Base/Limit MSR (FS_BASE_MSR)
GS Segment Base/Limit MSR (GS_BASE_MSR)
LDT Segment Base/Limit MSR (LDT_BASE_MSR)
Temp Segment Base/Limit MSR (TEMP_BASE_MSR)
TSS Segment Base/Limit MSR (TSS_BASE_MSR)
IDT Segment Base/Limit MSR (IDT_BASE_MSR)
GDT Segment Base/Limit MSR (GDT_BASE_MSR)
SMM Segment Base/Limit MSR (SMM_BASE_MSR
DMM Segment Base/ Limit MSR (DMM_BASE_MSR)
