1a. evaluate hardware configuration structure of BIST ROM
    (this is a software structure reflecting the chip HW structure)
1b. run internal selftest BIST
1c. verify outer bus interface
    (i960 has an interesting check, boot structure with crc)
1e. start code of external bus

this is just needed for a monitor in external ROM.
