saravanababu22 · ‎02-12-2009

friends,

look into the below info

============

BOOT variable = ,1;s3223-entservicesk9_wan-mz.122-18.SXF8.bin,1;bootdisk:s3223-e

ntservicesk9_wan-mz.122-18.SXF8.bin,1;bootdisk:s3223-entservicesk9_wan-mz.122-18

.SXF8.bin,1;

CONFIG_FILE variable =

BOOTLDR variable does not exist

Configuration register is 0x2102

=========

what does this "BOOT variable = ,1" refer to, how to clear this boot var statement. i need to point it to single image followed by 1.

i want the output to be configured as

MSFC(boot)# show boot

BOOT variable = s3223-entservicesk9_wan-mz.122-18.SXF8.bin,1

CONFIG_FILE variable does not exist

BOOTLDR variable = bootflash:s3223-entservicesk9_wan-mz.122-18.SXF8.bin

Configuration register is 0x2102

kindly guide me

It's all part of the boot system command. Please refer to the documentation:

"BOOT variable = ,1" refer to command "boot system flash".

Type "sh run | i boot system" to see what boot statement in the current config. And then remove unused boot command. Then "wr mem" and check "show boot" again.

In your case remove the existing boot system commands and try the following one.

boot system flash:s3223-entservicesk9_wan-mz.122-18.SXF8.bin

boot system bootldr bootflash:s3223-entservicesk9_wan-mz.122-18.SXF8.bin

I assumed that the bootloader you mentioned in the output is correct.

Hope to help
