Probably, most guys here use BIOS Saver. And it works well? In mine, RD1 for PLCC gets not being writable suddenly. I mean, it seems writable but # flash_rom -v fails. I solved this problem by a quick hack.
How about yours? You can write RD1 or W49F002U well? Any problem happen?
I had to patch util/flash_and_burn/w49f002u.c:
@@ -42,7 +42,7 @@ erase_chip_jedec(flash);
printf("Programming Page: "); - for (i = 0; i < total_size; i++) { + for (i = 0; i < total_size / page_size; i++) {
Even after that it's sometimes a bit flakey and I have to erase, then write it. I've put the board's original BIOS in the RD1 and am writing to the SST 39SF020A instead, which works without problems.
I also tried to add Atmel AT49F002 support to flash_rom, which according to the data sheet should be very like the W49F002U. However I couldn't get it reliably working.
BTW, a cable of your RD1 is not broken? I needed soldering to fix it.
Mine was fine out of the box.
