Don't know if that is true or not. Ok.. but the tftp xfer takes like 7 seconds.. how long does the serial transfer take? I would think that a longer xfer might just be more likely to be interrupted. Anyway, doesn't the Cisco check the flash CRC checksums on reboot, before it ever does any re-programming? You'd think that would make bad transfer a non-issue. -.bill.layer.- -.those who are talking don't know, and those who know aren't talking.- -.frogtown.- -.minnesota.- -.u.s.a.-
