1. BIOS. BIOS boot program is started automatically, and it attempts to find and load what is called the master boot record (MBR), mboot, from the first sector in the boot device. An error is displayed if the mboot file does not exist.
2. Boot programs. The mboot program load the Solaris boot program called pboot, which in turn loads the primary boot program, bootblk, whose purpose is to load the secondary boot program located in the UFS file system. /etc/bootrc presents a number of choices for booting the system, and you have 5 seconds to specify a boot option or to start the boot interpreter. The default choice is to load the kernel.
3. Kernel initialization . After the kernel has been loaded, it initializes itself and uses the secondary boot program boot.bin (or ufsboot) to load system modules.
4. init. The /boot/solaris/bootenv.rc contains the eeprom variables used to set up the boot environment on an x86 machine. All directories and files needed to boot an x86-based system are contained in the /boot directory.作者: zhmzhouming 时间: 2010-11-21 12:41
ILOM和BIOS不是一个概念啊，ILOM相当于BMC，插上电源线，不需要按power按钮他就上电了。作者: ahsflp 时间: 2010-11-24 20:31 回复 2#小鹭
