Here is a little tip for memorizing I/Os for COM 1-4 and LPT 1 and 2:
Just remember this single code: 323232-FFEE77 Then put the first set of numbers in a column. 3 2 3 2 3 2 Now put the second set in a column to the right. 3F 2F 3E 2E 37 27 Now add the number 8 to each one 3F8 2F8 3E8 2E8 378 278 In order, those are the addresses for COM 1-4 and LPT 1 and 2. COM1: 3F8 COM2: 2F8 COM3: 3E8 COM4: 2E8 LPT1: 378 LPT2: 278 When you sit to take the test they give you scratch paper. Write this out on the scratch paper when you start and you have a little reference for the whole exam. |

That's a very nifty trick! Plus my question about getting something to write random information on gets answered too. Thanks for the useful info.

Thanks for the useful info. while taking the exam you might get a whiteboard instead of scratch paper depending on the facility. When memorizing lists I find it helpful to make a sentence of the first letters of each item in the list. For example Ports Paralllel COM Serial USB IEEE1394 People perpetually consider surprising unicorns intentionally. Then dump on white board. you can add as much information as you wish with additional sentences. This also helps you remember the entire list as the first letter of each item is accessible. This memnonic device prevents remembering only six of the seven dwarfs syndrome. -------------------- None shall pass! None shall pass!

Absolutely helpful. Are there any more such tips with listed stuff? e.g. DMA modes, IRQs, SCSI, Sockets, Error codes etc

 Fantastic tips.. taking the test in December, all of this will be extremely useful.. The acronym in a sentence is used widely, but I have trouble remember all the sentences.. if you say it enough, you finally get it though.. its been used in high school to memorize lots of things! |

Now that's just what I've been looking for! I've been getting the input output addresses wrong for an eternity and now you lot have given me the missing link of tricks.
Keep em comin!
