This section describes the function and displays the syntax of each command used to load and copy system images, microcode images, and configuration files. For more information about defaults and usage guidelines, see the corresponding chapter of the Router Products Command Reference publication.
async-bootp tag [:hostname] data
no async-bootp
Use the async-bootp global configuration command to enable support for extended BOOTP requests as defined in RFC 1084 when the router is configured for SLIP. Use the no form of this command to restore the default.
| tag | Item being requested; expressed as filename, integer, or IP dotted-decimal address. See the async-BOOTP tag keywords table in the Router Products Command Reference publication for possible values. |
| :hostname | (Optional) This entry applies only to the host specified. The argument :hostname accepts both an IP address and a logical host name. |
| data | List of IP addresses entered in dotted-decimal notation or as logical host names, a number, or a quoted string. |
b

b flash [filename]
To boot the router manually, use the b ROM monitor command.
| filename | Name of the system image from which you want to netboot. |
| ip-address | (Optional) IP address of the TFTP server on which the system image resides. If omitted, this value defaults to the IP broadcast address of 255.255.255.255. |
| flash filename | (Optional) Boots the router from Flash memory with the optional filename of the image you want loaded. The filename is case sensitive. Without a filename, the first valid file in Flash memory is loaded. |
[no] boot bootstrap flash [filename]
[no] boot bootstrap mop filename [mac-address] [interface]
[no] boot bootstrap [tftp] filename [ip-address]
To configure the filename that is used to boot a secondary bootstrap image, use the boot bootstrap global configuration command. Use the no form of this command to disable booting from a secondary bootstrap image.

To specify the location of the microcode you want to download from Flash memory into the writable control store (WCS) on a Cisco 7000, use the microcode interface configuration command.
| interface | One of the following interface processor names: aip, fip, fsip, hip, mip, trip, eip, or sp. |
| flash | (Optional) If the flash keyword is specified, a filename argument is required, unless you are using the no microcode interface-type flash command. |
| rom | (Optional) If specified, no further arguments are necessary. For example, the command microcode fip rom specifies that all FDDI Interface Processors (FIPs) should be loaded from their onboard ROM microcode. This onboard ROM microcode is not the same as the eight ROMs on the RP that contain the system image. |
| system | (Optional) If specified, the router loads the microcode from the microcode bundled into the system image you are running for that interface type. |
| filename | (Optional) Filename of the microcode in Flash memory you want to download. This argument is used only with the flash keyword. If you use the flash keyword, the name of the microcode file in Flash is required unless the command is no microcode interface flash. (This command results in the same default condition as the command microcode interface rom, which indicates that the card should be loaded from its onboard ROM microcode.) |
