Comment 6 for bug 1316068

Yes, I am sure.
To be 100% certain, I reinstalled grub 2.02~beta2-9, and tried the following commands, as typed here after the * with no extra characters:
* ls
* ls -l
* lspci
* vbeinfo
* hello
* help
* functional_test
* all_functional_test
They _ALL_ answered by "error: disk 'hd0,msdos5' not found."

Pressing <TAB> key on the grub command prompt gives a list of commands. Auto-completion of the command works as well.

The BIOS boot mode is set to "LEGACY+UEFI", if that matters.

The grub config file is functional since it is used by my supergrub2 disk to boot the system.
