Is there a way to kind of "flash" a new bios with a softmod, if so can you tell me how or point me to a tutorial?

EvoX dash has a bios flashing utility.......but i am not sure if it can flash to the modchip/TSOP after booting into evoX through softmod.

I had booted through modchip to evox...then turned the chip off to flash TSOP.

Phoenix BIOS Loader is a little app that will load any bootable-from-media BIOS into memory to replace the current one. Depending on which softmod you're using, it may already be installed. If so, then you can simply switch the BIOS .bin file, otherwise you'll have to install it and find a suitable BFM BIOS. More modern softmods use nkpatcher, which simply patches the retail MS kernel. This actually offers more options on a softmod, if you're already using it, you can tweak the settings.

Basically, which softmod package are you using, and why do you want to change the BIOS?
