usb boot

[aspenjim]

would someone kindly explain how plop emulates a bios in order to boot to a usb flash drive, when if the bios didn't support usb booting in the first place, it would never be able to read the flash drives boot sector(s).

i found the answer to my own question...  adding plop bootmgr to boot.ini .

if anyone wants to further explain, that would be great.   thx
