Edge Posted February 26, 2021 Report Share Posted February 26, 2021 (edited) So I recently learned a valuable lesson about TSOP flashing when I flashed my 1.0 with iND-BiOS.Beta.Feb-11-05.67.bfm.bin rather than the non-BFM version of the bios. I was wondering what the practical purpose of the BFM (Boot from Media) bios is, and how one would even use it? I'm assuming it is a BIOS that something can load AFTER the Xbox as already booted and initialized all hardware?

KaosEngineer Posted February 26, 2021 Report Share Posted February 26, 2021 You run the Phoenix BIOS Loader (PBL) to switch BIOS/kernels that run from RAM. You use BFM BIOSes with PBL. 1 Quote Link to comment Share on other sites More sharing options...
Wally12 Posted March 2, 2021 Report Share Posted March 2, 2021 (edited) ind-BIOS 5004.06 is another one to stay away from. It’s known to brick and it happened to me. Edited March 2, 2021 by Wally12 Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted March 2, 2021 Report Share Posted March 2, 2021 You can also load a debug BFM BIOS to change your console from a retail device into an Xbox Debug Kit. Operation of a retail console as a debug kit works better if it has an additional 64MBs of RAM added (v1.0-1.4 consoles only) bringing in par with a Debug Kit's 128MBs of RAM. I'm not exactly sure how limited a retail console is when being used as a debug kit with the stock 64MBs of RAM. Quote Link to comment Share on other sites More sharing options...

Does anybody have an answer? On topic, why would one use a bfm? Why do newer installers use them? Quote Link to comment Share on other sites More sharing options...
sweetdarkdestiny Posted January 7, 2022 Report Share Posted January 7, 2022 There are some reasons to use a BFM bios for an installer. Mainly, you can make use of things which are not supportet by the bios the user have on his mod chip or are not active. You can make sure it's a .67/FG bios in case the user uses a old bios which dosn't support partition 7 (Happends every now and then). You can make use some gimmicks which would not be possible without a BFM bios (Disk swap for example which is usefull if you like to make an addon disk which can be side loaded in the main installer (Damn spoiler )). And like Kaos already wrote, you can use also a debug bios to run an debug dash on your console which for the most pll doesn't make any sense. Over all, for 98% of the users which just like to use there xbox to play games, a BFM bios has no use. 1 Quote Link to comment Share on other sites More sharing options...
