I have a 3725 which has missing flash card: it boots to ROMMON only; if I get a new compact flash card - how do I format it first to enable me put an IOS version on it? Should I be able to boot from "internal" memory ?
3725 Flash - won't boot

It appears that the 3725 has no internal flash and so can not boot IOS without a compact flash card *unless you do a network boot*.
I am not sure, however a quick search suggests that there is no rommon 'format' command. The best idea might well be to do a network boot (tftp or otherwise boot) and then format the flash from IOS.
If you can't find the documentation that describes how to do a network boot please come back for further info. I would describe it here if I could, but I need to look it up so you may as well do that yourself:-)
Bear in mind that tftp is limited to 64M (or 32M if you have old kit). tftpd32.exe (tftpd32.jounin.net) is pretty cool 'n' groovy.
