I have Sun Sparc20 with with operating system SunOS414.
I could boot up the system in the beginning, but I got the error as
below these couple days.
Checksum 9248dc5e != 4884dac, trying to boot anyway
Instruction Access Exception

And, I try to use boot use CD, on OK prompt I enter boot cdrom. I got
the same error as above: checksum ......., tyring to boot anyway

Is this hardware problem or my disk has problem?
Please help. Thanks.

Randomly searching the web, I came across a mentioneing of the
phrase "trying to boot anyway" on the sunmanagers mailing list
(form 1997):

The probelm appears to be related to the bootblock. Installing
a new bootblock helped the person writing the above summary, but
I don't know if it helps you.
