New! grub4dos eBook (PDF).
The E2B menu system uses grub4dos:
- grub4dos should not be confused with grub or grub2 even though these all display the grub> prompt as the command line interpreter prompt.
- grub4dos uses the BIOS to access hardware (although it does have it's own USB 2.0 driver if you install it).
- grub and grub2 are 'linux-like' and load their own drivers.
- grub4dos cannot be booted from UEFI - grub2 can both MBR and UEFI-boot.
- grub4dos is actively maintained and improved.
- grub4dos has commands such as dd and partnew and can write to storage devices
- The \grldr file contains the bulk of the grub4dos code. Just change this file to change the version of grub4dos.
- E2B will use a tested and validated version of grub4dos (\grldr file). Do NOT use a different version.
- grub4dos 0.4.5c is an older version. grub4dos 0.4.6a is the new and continuously improved version.
