"CS" or "Master and Slave"?

My eMachine 1860, running WXP, has been flakey on boot for a year

everytime.

I took it in to the shop. They found a cable was nicked and the
jumpers
were wrong. They set them to Master and Slave. Now all is well.
However, I checked the manual and it says to set the jumpers to "CS".
The shop says the manual is wrong.
Does it matter as long as the machine is working? Presumably the
nicked cable was the problem the whole time.
Thanks.

If your BIOS has no problem with it, setting the jumpers to Cable Select
(CS) is simply convenient if you swap drives, remove drives, add drives
etc. It just means that you won't have to manually set the jumpers, that
the position (1 or 2) a drive has on the cable determines wether it's
slave or master. There's nothing wrong with setting the jumpers to Slave
and Master respectively, the end result is the same. CS is just easier -

if it's supported by the BIOS.

Clueless.
The bios has nothing to do with it.


Ah, the socially retarded troll boy! You're such a fool - to think
you'd actually say this, LOL! Oh, I'm glad I somehow failed to add you to
my killfile on the last pathetic ramble you spewed out, otherwise I
wouldn't have seen this. LOL Hee hee hee Ahhhh...

Now let's see if I can get you added to that killfile of mine this time...
Oh yeah, that's the stuff!

Actually, for once he's right. Cable Select is not a BIOS function, it's
hardware, the IDE equivalent of the twisted cable that is used for diskette
drives. The only difference between cable select and jumpering for
master/slave is that when cable select is used which is master and which is
slave is determined by the position of the drive on the cable instead of by
an explicit jumper setting.

If the manual for your BIOS says to set the
jumpers to CS, then it obviously supports Cable Select, so it would be
the shop who is wrong, not your manual. But either way, it makes no
difference once the system is up and running.

Cable Select also requires a cable that supports it. I think most of

The second sentence in the next paragraph, which you snipped, was
"For*cable*select*to*work*one*conductor*has to be cut at a certain point."

Or the appropriate pin removed from the connector...
