How old are your teachers lesson plans?

Jumper Free technology has been available for over 5 years on motherboards.

In test instruments, even calibration has been fully under software control for over 10 years. I even have some computer based instrumentation systems that had software calibration back in the 80's.

I suspect that the age of jumper free technology is at least part of why you are having trouble finding information.

Also, to get better assistance, please let us know what the course is, and the general context of the question. If the research we point you to is not relevant to the course, it does you no good.

I think we are in the same class. I can not find a clear answer to that question.

The computer I built with a Cyrix 166Mhz processor (Pentium I equivalent) had a jumperless MB. If I recall correctly I built it around 1997. It was definately one of the selling features of that motherboard (QDI I think) that it was jumperless.

Frankly I think it was more of an issue back then as you had to juggle IRQs on NICs and so on.

Today its assumed that you can set everything from the BIOS, but that wasn't always the case. Disable/enable onboard sound/video/NIC was often done by jumper in the old days.

Of course I never had to jumper anything in a mac. You could add cards, switch from onboard video to a card etc without ever using a jumper. That was due to Apple's plug and play technology - your devide had to conform to Apples standards or it wouldn't work.

That was also on a jumperless mobo. [ 1996 ]

Thing that amazed me ( and now stuns me!!) was that Win95/Win98 absolutely FLEW with that hardware in 16MB of memory and 8MB VGA card, WD 540MB + Seagate 810MB HDs.

Compare that to contemporary systems with twin core 2GHz, 1GB memory, 128MB onboard video, 100s of GBs of HD - and watch Vista c-r-a-w-l...!
