[SunHELP] 'Bad Slots' on Enterprise 6500 and 3500

[David Froman]

Yes, if slot 7 is empty the 3500 will boot normally.  I can take a board 
that was in slot 7 and place it in any other slot with no issues.  I can 
take any good board and put it in slot 7 and will receive the memory errors.

Same with the multiple slots on the 6500.

Thanks
Dave
