zbootcfg
NAME
zbootcfg − Modifies the boot parameters of the OpenArchitect switch.
SYNOPSIS
zbootcfg -a | -d <device number> [<boot_string>]
DESCRIPTION
zbootcfg is used to display or modify the boot parameters on the switch. The boot parameters
are utilized by the minof boot loader application to indicate on which device to find a boot image.
Care should be taken when changing the boot string. Incorrect procedures can result in a switch
that cannot boot.
-d <device_number>
Three ROM boot devices are available in the switch. The factory-
shipped boot device is 1. The following describes each boot
device:
-d 1 Boot image located at offset 0 in the application flash 1.
This is the factory-shipped location of the primary OpenArchitect
image.
-d 2 Loads an image located at offset 0 in the application flash
2. This is the factory-shipped location for the alternate
OpenArchitect image.
Any characters after the -d <dev> parameters are saved in flash memory and passed unchanged
to the booting kernel.
OPTIONS
-a Displays the current boot string. The default factory
shipping string is “dev1.”
-d <dev> Specifies the ROM device from which to boot. The <dev>
value must be the number 1 or 2 corresponding to application
flash 1 or application flash 2, respectively.
<boot string> Optionally, a boot string may be provided that is
passed to the booting kernel. All characters after the -d <dev>
are passed unchanged to the booting kernel.
