GRUB and the Solaris Operating System on x86 Platforms - A Guide to Creating a Customized Boot DVD (pdf)
GRUB, the open source GRand Unified Bootloader, has been used for years in Linux and various versions of BSD as the standard file system-aware boot loader for open source operating systems. GRUB’s implementation in the Solaris OS is similar to the implementation in these other operating systems. One major difference in the Solaris OS implementation of GRUB is the ability to traverse a UFS, the standard file system used in the Solaris OS. The UFS code for GRUB was written by Sun and is available as open source via the OpenSolaris initiative.
This article describes GRUB and its implementation for the Solaris Operating System on x86 Platforms. It provides a sequence of procedures that can be followed to customize a DVD using this framework.
