Other changes that support Fast Reboot on the x86 platform include the new uadmin function, AD_FASTREBOOT. This function resets the system, enabling the reboot command to bypass the BIOS and the boot loader phases.
The uadmin 2 8 command has limited functionality. If the command is used to facilitate a fast reboot of the system, neither the boot archive, nor the menu.lst file are updated. For this reason, the reboot -f command is the preferred method for initiating a fast reboot.
For more information, see the uadmin(2)man page.
