Hello!
Believe itor not I've jsut been learning how to fix this. You need to re tattoo the DMI. I work for "The Tech Guys" in England. If you give me your serial number for the computer and the part number on the disk I should be able to help you through it. I know that sounds a bit dodgy, so 'll tell you the way it's done so hopefully you can trust me.
When you get the C: prompt type q: then enter
then type CD DRIVERS and enter
then type TATTOO/INTHSPRETEST and enter
then type TATTOO/CREATEDMIFROMHS and enter
then type CD.. and enter
then type EXTHS/RESTORE
now for the next piece of info you'll need to give me your seriel number and the number on the diskette or cd or dvd or whatever because I can use a bit of software that recalls all the details you need to make the Tattos match on all parts of your system.
Anyway, I hope this helps.
You can find out your seriel number on either the back of your PC or in a program called snapsys and it should tell you in there I think.
Hope this helps so far!
