“EFLAGS Register” currently states:
Bit 11 “OF” as “X”
It should state:

Chapter
3, Section
3.9, third paragraph currently states:
As is shown in Table 3-3, the following flags must be set or cleared to enable the PSE-36 paging
mechanism:
•
PSE-36 CPUID feature flag-When set, it indicates the availability of the PSE-36 paging
mechanism on the IA-32 processor on which the CPUID instruction is executed.
•
PG flag (bit 31) in register CR0-Set to 1 to enable paging.
•
PSE flag (bit 4) in control register CR4 - Set to 1 to enable the page size extension for 4-
Mbyte pages.
•
PAE flag (bit 5) in control register CR4-Clear to 0 to disable the PAE paging mechanism.
It should state:

•
Or the PSE flag (bit 4) in control register CR4- Set to 1 and the PS flag (bit 7) in PDE- Set
to 0 to enable 4-KByte pages with 32-bit addressing (below 4GBytes).
