Hi. I've been trying to change the default boot mode from UEFI to Legacy on a notebook. I changed it to Legacy through AMIBCP & flashed it using AFUDOS mod.rom /GAN. To my surprise the default was still UEFI. Saving the bios & reloading it back to AMIBCP I found it was set for Legacy. Through tones of reading I've found that I need to use AMIDOS to change the defaults. I've had a look at specs for SMBIOS but can't find a simple Table/info on how to do this. Anyone have any ideas?
Hi Flipp3r, it depends on your hardware, but I prefer using amidewin. You can find it at the BIOS Tools section of this forum. best regards
I do all my flashing from dos so may as well do this too. What do you mean "depends on your hardware"? Is it different per manufacturer? Can the fields change per motherboard?? Thanks
The DMI/SMBIOS tools aren't going to let you change your default boot mode. The CMOS editing tools might though (SCEDOS/SCEWIN/SCEWIN_64).
MSI Support have emailed me the following command to change default from UEFI to LEGACY: Code: AMIDEDOS /os 2 $BIOSE0200000000000000000 I can't find anything usefull online about this command. The AMIDEDOS Rom Utility Guide lists /OS command as "OEM String (Type 11) System Configuration Options". This is the 1st time I've had to do this so I'm thinking this is very specific to the model notebook I have (MSI CX70 2QF).
Neat. Some motherboard manufacturer's used to store sysconfig info there (ASUS and MAC address...etc). I didn't think they still did that.
