Tim and Unknown are very brave. Except maybe video connection, I won't
try others I believe to be no-no.
Here is another one:
Would it be OK if you disconnect/connect the power of internal IDE device
(eg. IDE HD, IDE CD-ROM) while the computer is on?
How about connecting or disconnecting the IDE cable while the computer is
on?
I think the first one might be OK, but the second one is probably very
unsafe.
What are your experiences on these 2 issues? I have not tried either and
I probably won't either.
