Uniflash issue with larger capacity flash ROM

[ruelnov]

Hi, Rainbow.

After having used Uniflash for practically all the hotflashes I did for several months now, I could now give it an A rating. This is my own personal rating, however.

Also, if you could help me how to flash a 256Kb bios image into a 512Kb flash ROM, that would be much appreciated.

Uniflash v1.38 complains about this size difference, and aborts the flashing procedure. But all I got is the 512Kb flash ROM to rescue an Asus P4T mainboard, and all bios images posted at Asus website for this board are only 256Kb in size.

Thank you for your help.

Then it's most probably not correct BIOS for that board - might be OEM version of some kind. You might try to create 512KB file by padding it with 256KB of FFh bytes at the beginning (create 256KB file of FFh bytes, then join with the BIOS - "copy /b ffh.bin 256kb.bin 512kb.bin").

Yeah, it worked.

But can't this be done automatically within Uniflash in future versions?

I mean, instead of prompting a "size mismatch" error message why not prompt to "create 512KB image" for flashing?

UniFlash has no way to know where you want the 256KB image to be in the 512KB chip. For example, you might want to flash a chip for a device with bottom boot block. Thing like this are best done outside flashing tools.
