To Luvhuffer and Raybay, you're both right depending on how system specific any given computer builder makes their installation/recovery CDs. With the "sysprep.exe" tool and an appropriate number of product licenses and keycodes purchased from Microsoft, the said builder can make their CDs as model number and hardware build specific as they want. Drivers, Programs, Applications, even optional Windows components can be specific to a particular model's recovery CD(s). Or they can be as generic as they'd like as well. As far as PROM's, EPROM's, and EEPROM's go though. Raybay? PROM's are the progammed one time only chips. EPROM's and EEPROM's can be reset or changed. PROM stands for Programmable Read Only Memory, EPROM stands for Erasable Programmable etc,etc. EEPROM, Electronically Erasable etc, etc. Bios's, chipset's, and boot up initialization are comprised of examples of all three. In today's new HD TV's I can go into factory menus and change certain settings, reset others to default, and others are set when the IC's are initially created and shipped to the manufacturers. For example I programmed a Sony 32" I recently worked on to think it was a higher model set with more features than it initially have, but I had a 37" Philips plasma that I had two similar logic boards for, one was for a 32" the other was for a 37". The section that contained the data that discerned the differences between the screen sizes was burnt into the PROM from the factory as wasn't able to be altered. I hope this helped some, I ran across your posts while reading about another matter...take care...
