[comp.sys.ibm.pc] Questions about speeding up an IBM AT

m-liu@madonna (Micky Liu) (05/15/87)

I'd like to speed up a friend's IBM AT, but what I've heard is that I have
to have an old 6Mhz IBM AT before the ROM change that checked the clock.
I've heard that if I have either a 6Mhz AT with a modified ROM or an 8Mhz
AT, that I cannot speedup the machine simply by getting a faster clock.

So my questions to you are:

 1)  Is the above information correct?
 2)  Is there a way I can determine the ROM date and speed of my cpu and
     memory?  I've heard rumors about a program to do this, where is it?
 3)  Are there other nice ways to speed up AT's relatively inexpensively?
 4)  If I find out that it is already a 8Mhz AT what can I do?

Please email responses directly to me.  I will summarize if I get requests
to do so.  Thanking you all in advance!!!
