Information in this document applies to any platform.
This document addresses an issue where a Solaris 10 x86 system does not boot due to a corrupted (too small) boot_archive.
The below error message is seen on the console, shortly after GRUB menu disappears:
diskread: reading beyond end of ramdisk start = 0x2000, size = 0x2000 failed to read superblock diskread: reading beyond end of ramdisk start = 0x8000, size = 0x800 failed to read superblock panic: cannot mount boot archive Press any key to reboot
And the system is not able to boot. Pressing a key to reboot does not result in a successful boot.
Solaris 10 Update 1 introduced the GRUB bootloader and the boot_archive for the x86 platform systems.
This new functionality is also delivered through a set of patches, see: Solaris 10 x86 Platform GRUB Bootloader Architecture and Kernel Patch 118844-27 or Later (<Document 1000670.1>)
