I recently obtained a 2851 and have been battling this issue for a week now. An odd set of circumstances happen with the bootstrap startup process. If the router has loss of power or when reloaded; it fails to read the CF card and boots to rommon. I can tftp an image to it (tftpdnld -r) and IOS CAN read the flash card along with any saved configuration.
In fact once in IOS, I can wr mem and print the hardware details of the CF card. Once I reload the router it goes to rommon, fails to open the flash, then sits until i tftp the image back. When the router load IOS, it also loads the startup config.
I don't think it's a problem with the CF card as IOS can read it. I've tried formatting the card from IOS and from my pc as FAT, FAT16, FAT32, and NTFS - it didn't make a different. I updated the ROMMON to allow for USB booting but haven't purchased a USB Drive yet for testing. The upgrade didn't resolve this issue either. It almost seems like a firmware problem with the EPROM.
I've played with the config register to see what, if any, impact it had. Currently it's set to 0x2102, putting it in the diag register didn't produce any other errors than what's listed below.
I'm stumped and out of ideas. Hoping somebody has some insight on what could be causing this to happen.
Apprecite your time reading my question.

Thanks Guys,
I have returned my two 258meg cisco CF cards to ebay for full refund and ordered two brand new cards for my lab,
everything is so much simpler using usb and CF.
Cheers Mike
