Booting the AGM
The factory configures the AGM to automatically load a Cisco IOS image the first time you insert the
module into a Catalyst 4000 family switch. The software configuration register in the AGM determines
where to find the image. The factory sets this register to load the IOS image into bootflash from
configuration register 0x0101. This register enables autoboot at register 0x0103.
