which _OEMAddressTable do you modify??
1) the one under public\csp\x86\i486\oeminit.asm or
2) the one under platform\common\src\x86\common\startup\startup.asm

The CEPC in PB 5.0 is a PQOAL BSP, and it is not using the i486oal library
provided by the csp directory.
The _OEMAddressTable in PQOAL arch. is defined in the
platform\common\src\x86\common\startup\startup.asm
