Flash Disks and Flash Memory Cards in the GRP
78-4339-09
Implementing Additional Configuration and Maintenance Tasks
Caution The Flash memory card or Flash disk does not insert all the way inside the GRP; a portion of the card
remains outside of the slot. Do not attempt to force the card past this point.
Use the following procedure to remove a Flash memory card or Flash disk:
Step 1 To eject the card, press the ejector button until the card is free of the connector at the back of the slot.
(See Figure 14c.)
Step 2 Remove the card from the slot and place it in an antistatic bag to protect it.
Notes About ATA Flash Disks
Note the following issues when using an ATA Flash disk with Cisco IOS Releases prior to 12.0(22)S:
• Cisco IOS Release 12.0(17)S or 12.0(17)ST or later is required, along with the corresponding boot
images for the GRP to function with a Flash disk. Flash disk system boot support is provided only
in the IOS bootloader.
• In ROM Monitor version 181 or earlier, the Flash disk file system is not recognized.
• If you upgrade to ROM Monitor version 182 or later, you must also format the Flash disk with
Cisco IOS Release 12.0(22)S or later.
ATA Flash Disk Boot Image Support Requirements
A boot image that supports the ATA file system must reside in bootflash. To enable booting from a Flash
disk, set the configuration register bits to 0x2102 and add a boot system command to the configuration
as follows:
Router(config)# config-reg 0x2102
Router(config)#^Z
Router#write mem
Router# configure terminal
Enter configuration commands, one per line. End with CTRL-Z.
Router(config)# boot system disk0:gsr-p-mz.120-19.S
Note See the Cisco IOS online publication Loading and Maintaining System Images and Microcode for
details on this procedure.
Formatting a Flash Memory Card or Flash Disk
The Flash memory card or Flash disk that shipped with your router contains the Cisco IOS software
image you need to boot your router. In some cases, you might need to insert a new Flash memory card
or Flash disk and copy images or backup configuration files onto it. Before you can use a new Flash
memory card or Flash disk, you must format it.
Note In the following procedure, you are assumed to have already booted your router. Use only linear Flash
memory cards, or ATA Flash disks.
