I’ve had problems resetting the password on a 7606 Sup720-DFC-3BXL. I would do the normal break and confreg 0x2142, but it would continue to boot with the old config, refusing to bypass. The fix is that there are two places to issue the break sequence. At the initial boot, but also when it says “Download Start !!!!”. When you see the download start, do the normal break sequence and follow the normal reset process.<\/p>\n
