Hello,

I've a cisco PIX515 6.3(5) with some kind of image problem.

I've issued "no access-list" in config t and it stopped responding.

It generates output below end reboots over and over.

I have tried to upload pix635.bin image file to it but this does not help.

Rebooting....

Use BREAK or ESC to interrupt flash boot.

Use SPACE to begin flash boot immediately.

Reading 1974784 bytes of image from flash.

When a PIX experiences a continuous/boot loop, you cannot gain access to the PIX and error messages scroll until the unit is powered off. A continuous loop might be due to a hardware issue.The This link shows an example of a good boot and two examples of a bad boot due to hardware problems and a provided solution.
