|Subject:||the rootcause of the grub2 that can support USB keyboard|
|Date:||Tue, 21 Aug 2018 07:42:17 +0000|
Rencently, I have learned the GRUB2. And I have a question about it.
The first experiment:
Sata : MBR format
I have read the grub-2.02 source code and I find the core.img including the modules : ext2 part_msdos biosdisk
I delete the grub.cfg in the “/boot/grub/grub/cfg”,so the system will enter the command-line of the grub.
So the grub only has modules as followings:
Name Ref count Dependencies
Normal 1 buf io,gettext,terminal,crypto,extcmd,boot
Ext2 1 fshelp
But I have found the USB keyboard module-usb_keyboard.mod that I don‘t load ,
So why the usb keyboard can be used when I don’t load usb modules?
