Through

RTL8019AS

From

ISA Bus

In this case, the BROM page mode is used. Before either to read or write BROM, the appropriate ROM page

must be set in the BPAGE (page3, offset 02h) register first. The RTL8019AS will always reflect the content

of BPAGE onto the BA14-21 bus. When RTL8019AS decodes a valid BROM read or write command, it

asserts BCSB low. Note the flash memory write must be enabled through the RTL8019AS's FMWP register

before the host's flash write command.
