Rsfc Boot Process - Cisco Catalyst 5000 Series Installation And Configuration Note

RSFC Boot Process

When you boot a Catalyst 5000 series switch with an RSFC installed, the following process occurs
on the RSFC:
The ROM monitor image loads and checks the value of the configuration register boot field.
1
If the boot field equals 0x0, the boot process ends and the system remains in ROM monitor mode.
If the boot field equals 0x1, the ROM monitor proceeds to Step 2.
If the boot field equals any value between 0x2 and 0xF inclusive, the ROM monitor proceeds to
Step 3.
2 The ROM monitor checks the contents of the BOOTLDR variable.
If one or more boot helper images are specified in the BOOTLDR variable, the ROM monitor
attempts to locate and load the images in the specified order. The ROM monitor loads into RAM
the first boot helper image that is successfully located and is a valid RSFC boot helper image file
and then proceeds to Step 4.
If the BOOTLDR variable is empty (no boot helper image is specified), if none of the specified
boot helper images can be located, or if none of the specified images are valid RSFC boot helper
images, the ROM monitor proceeds to Step 6.
The ROM monitor checks the contents of the BOOT variable.
3
If one or more system images are specified in the BOOT variable, the system attempts to locate
and load the images in the specified order. The system boots the first image that is successfully
located and is a valid RSFC system image file, and the boot process ends.
If the BOOT variable is empty (no system image is specified), if none of the specified system
images can be located, or if none of the specified images are valid RSFC system images, the
system proceeds to Step 5.
The boot helper image checks the contents of the BOOT variable.
4
If one or more system images are specified in the BOOT variable, the boot helper attempts to
locate and load the images in the specified order. The boot helper boots the first image that is
successfully located and is a valid RSFC system image file, and the boot process ends.
If the BOOT variable is empty (no system image is specified), if none of the specified system
images can be located, or if none of the specified images are valid RSFC system images, the
system proceeds to Step 6.
The ROM monitor attempts to load the first image in bootflash:.
5
If there is a valid RSFC system image in bootflash:, the ROM monitor boots that system image
and the boot process ends.
If there is not a valid RSFC system image in bootflash:, the boot process ends and the system
remains in ROM monitor mode.
6 The boot helper attempts to load the first image in bootflash:.
If there is a valid RSFC system image in bootflash:, the boot helper boots that system image and
the boot process ends.
If there is not a valid RSFC system image in bootflash:, the boot process ends and the system
remains in boot helper mode.
