Re: jmp INSTRUCTION IN boot.c fails and resets again , what could be the reason.

I have enabled RAMTEST(ramtest.inc) in the LinuxBIOS, it seems to be running at
a very slow pace.Hope it finishes off by today.

The number(887?????) increments at a very slow pace and has
been more than an hour now. Moreover, I have 64MB ram, 
does the above range of test look OK.
If has basically happened after changing some parameter
in the North Bridge.
I have run ramtest before as well without the changes.

But in this case also, it used to reset...
I hope, this what is expected in the Successful Output of Ramtest.

Any pointers on this one.

jmp INSTRUCTION IN boot.c fails and resets again , what could be the reason.

RAMTEST is useful, but for real testing, you need memtest86.

I hope your change fixed the problem.

RAMTEST is usually good enough to catch errors so bad you
can't get past the BIOS without fixing them.

Agreed. But the part in question has proved in the past to be unusually 
difficult (for me anyway) to get working. For this case I think memtest86 
is appropriate.
