Hello,
I have been working on getting my RTL8019AS based board to remember what MAC address I was giving it before I realized that the
8019AS does not have internal PROM and I would be forced to use an external EEPROM just to store the MAC. I have been reading the RTL8019AS data sheet along with the corresponding 'software developer's guide' and I am a little confused on how to program the EEPROM (9346). I know I want to program bytes 04H-09H on the 9346 with my 6 octets, and the data sheet says I can program the chip through my ISA bus, and the 8019AS. I kind of think its silly having a board that you can set almost anything with jumpers but requires an external EEPROM to store the MAC address (I have to read these datasheets closer!). Any help anyone can give would be much appreciated.Thanks, Matt
