The IA32 build of the EmulatorPkg for VS20xx does not boot because the default value of PCD PcdPeiServicesTablePage rarely succeeds to be mapped on IA32 Windows Host Environments. Change the DEC default value for this PCD to a value that is compatible with Windows and POSIX host environments for IA32 and X64. For IA32 builds, this 64-bit PCD is truncated to a 32-bit value. PcdPeiServicesTablePage is changed from 0x1003000000 to 0x1013000000. With this new value, no boot failures are observed. However, the use of this hard coded value can potentially cause a boot failure if this address specified by the PCD is already allocated in the user process.
