This may be too late, but here goes anyway. First, an "invalid system disk" message is not the same as "disk boot failure message". But you are getting both messages. Lets look at this in reverse order: Either of these two error messages may the result of the new motherboard not recognizing the correct speed of your CPU, but that's not the only reason for getting these error messages. It could be something else. But, these two messages would not cause the motherboard not to recognize the correct speed of your cpu, therefore we should first correct the speed problem, which may correct the other problem of the invalid system message. If not, you may want to return here for some more help. The speed problem is most likely connected to the jumpers on your motherbiard. I am assuming the new board is a current board, lime a 1998 or 1999 board and will actually accept a higher speed cpu than 75. So, read your user manula very carefully BEFORE changing nay jumpers. Changing the jumpers incorrectly may cause you severe problems. Review and understand the layout of the board as shown in the users manual and the actual biard itself before proceeding. In your manual look for the section that shows which jumper to change for your brand of CPU. Then, look for the section about the CPU BUS Frequency - find out where the junmpers are located. Study the section about CPU Frequency Ratio - study it. Look for the section about setting your barnd & speed CPU Voltage. All of these jumpers must be set in accordance with the instructions based on the brand and speed of your CPU. Be careful and take your time. Change only one "set" of jumpers at a time. You may have to change around 10-12 jumpers so you want to be careful and accurate. I use a hi-liter to mark my manula so I know which illustration to look at AFTER I've studied the manula and am sure which jumpers I need to change. Don't want to hi-lite the wrong pics. After you change the jumpers, your board should recognize your CPU correctly, and it may be that the invalid system problem is corrected too. Good luck!
