Intel IA-32 사용자 설명서

Vol. 3A 14-9

In processors with support for Intel EM64T, 64-bit machine check state MSRs are aliased to the
legacy MSRs. In addition, there may be registers beyond IA32_MCG_MISC. These may
include up to five reserved MSRs (IA32_MCG_RESERVED[1:5]) and save-state MSRs for
registers introduced in 64-bit mode. See Table 14-2.

IA32_MCG_ECX

182H

Contains state of the ECX register at the time of the machine-
check error.

IA32_MCG_EDX

183H

Contains state of the EDX register at the time of the machine-
check error.

IA32_MCG_ESI

184H

Contains state of the ESI register at the time of the machine-
check error.

IA32_MCG_EDI

185H

Contains state of the EDI register at the time of the machine-
check error.

IA32_MCG_EBP

186H

Contains state of the EBP register at the time of the machine-
check error.

IA32_MCG_ESP

187H

Contains state of the ESP register at the time of the machine-
check error.

IA32_MCG_EFLAGS

188H

Contains state of the EFLAGS register at the time of the machine-
check error.

IA32_MCG_EIP

189H

Contains state of the EIP register at the time of the machine-
check error.

IA32_MCG_MISC

18AH

When set, indicates that a page assist or page fault occurred 
during DS normal operation.

IA32_MCG_RAX

180H

Contains state of the RAX register at the time of the machine-check 
error.

IA32_MCG_RBX

181H

Contains state of the RBX register at the time of the machine-check 
error.

IA32_MCG_RCX

182H

Contains state of the RCX register at the time of the machine-check 
error.

IA32_MCG_RDX

183H

Contains state of the RDX register at the time of the machine-check 
error.

IA32_MCG_RSI

184H

Contains state of the RSI register at the time of the machine-check 
error.

IA32_MCG_RDI

185H

Contains state of the RDI register at the time of the machine-check 
error.
