Solution:

After I check with BIOS engineer, the fact is the PCA-6153 used UM8669 chipset, and its Super I/O will occupy the BIOS system I/O address 108h and 109h for extra software configuration programming. And the BIOS will do the initialization during system bootup to these address (according to CMOS BIOS setup settings). Unfortunately, this operation will affect the customer DIO card to function during system bootup. Due to this DIO card is using the same I/O address as Super I/O functions which are basic function to a system (unremovable), so it is recommended that customer should avoid to use 000h-1FFh system I/O address range. It is free to use add-on card on the range of 200h-3FFh. The PCA-6157 haas no this problem since it is using SMC FDC37C665GT chipset for Super I/O function, its I/O addresses are directly mapping to individual SuperI/O function. And the software configuration program for its software is done by these address. This chipset design structure is different to UM8669/UM8663 chipset. Normally, a PC will use system I/O address (without special mention in 000h-1FFh) to embed different chipset supply from IC supplier. And an I/O add-on card manufacturer will try to use 200h-3FFh for his product. This will prevent potiential I/O conflict for constructing a system. However, there are some add-on card suppliers are trying to use system I/O address for their product. To this kind of condition, It is recommended that you can select the product which has an ability to adjust its I/O address or IRQ, or DMA to prevent this I/O confliction. Summary, it is unable to provide any BIOS modification due to the chipset used on PCA-6153 will ocupy the I/O address the same as user add-on DIO card. As you can see this is a restricted limitation for UMC chipset on Super I/O function. Please consider to use different CPU card with SMC chipset or change another DIO card to solve your system confliction.
