128Kb ROM layout confusion

Hello,

Can you explain the order of the ROM(s) to be written to the AM29F010 EEPROM?

I have worked out ZBIOS is the boot ROM and should be at 0x1f000 to 0x20000 (4kb size) in the EEPROM but where should UNIBIOS, SIMPLEIO, U and UNIDOS be placed?

I haven't built the expansion board yet as the FPGA is hard to find in my country. I have output via the serial port and the serial bootloader prompt.
