There was a semi-secret firmware console which could be entered by typing “eatabug” on the Easy Setup welcome screen. The console resembled DOS (and also an EFI shell); it could access FAT-formatted floppies and hard disk partitions, as well as ISO-9660 CD-ROMs. It could execute external files and included a number of built-in commands to dump memory, read and write files, etc. There was also a simple debugger, although the disassembler had been removed from the ThinkPad firmware which made it rather less useful. On some SMS disks there was even a basic text editor.
UEFI, говорили они. EFI shell, говорили они. Новые технологии, говорили они.
