// To work around this problem, WOW is going to use the two bits of a
|

|
|
// 16:16 address instead of just one. We will set both these bits as 1 because
|
||
|
|
// with 3GB address space, the user mode flat addresses cannot have 11 as the
|
||
|
|
// first two bits. To achieve this, we will save the 2 most significant bits of
|
||
|
|
// the selector in the bit 1 and bit 2. We are able to do this because for WOW
|
||
|
|
// because both these bits have fixed values.
