	Now, this isn't an "officially" supported configuration
but it works..

	1) upgrade your bootflash: image to one that supports ATA flash
(eg: any recent 12.0S or 12.2S rsp-boot image)
	2) go to best buy and pick up a $13 CF <-> PCMCIA adapter
	3) while you're at best buy (or other electronics retailer)
pick up a 32-128m CF card
	4) insert into router, format disk0: 
	5) enjoy(*)!

* - The flash will be inaccessible from the rom monitor of a RSP, RSP2, RSP4
    due to lack of support for ATA/FAT filesystem.  You are using the
    boot loader for what it's good for, assisting this boot situation.

    RSP8 and others do have support, in that case, just use recent code
and enjoy.

	It's not a "tac supported" configuration, but as long as
you're not having problems booting your router, they're not going to
hassle you about how it was booted, and hopefully deal directly
with your real problem.
