The KB doc I am referring is follows
==== public/common/oak/drivers/pcmcia/mdd/window.c#2
(text) ====

781c781,782

pWin->pPhys->uBase+uCardAddress - WinState.uOffset : uCardAddress);
But it is different from you. If TI1225 can not boot, it usually cause by
BIOS. The BIOS is too old to recognize the TI1225 pci card. When Windows CE
boot on CEPC, it rely on CEPC to configure all the PCI device correctly.
