Your machine is not ready for XP. Since Microsoft didn't sell you your machine then you need to pester the supplier to FIX that 80 conductor cable message.
http://www.blackviper.com/Articles/OS/InstallXPHome/installxphome1.htm shows how to install XP, but if you have machine issues, then you deal with that first.
For me, I'd buy and install the right cable.
Why am I having such a hard time getting WinXP to work? I have installed XP at least 3 times and it works for a while(and it works great!) then quits and I go back to ME. I have contacted Microsoft via their email support group but they haven't been too helpful. Now it seems to have gotten worse. I have tried 3 or 4 time to install it as an upgrade and once as a new install but in all cases it gets to the point of installation and it dies. No disk activity or CDROM activity. Now by the point of insallation I mean the black screen with a wide dashed line across the bottom and a message that says something like "press f4 to install a third party driver for RAID or SCSI" I don't have either of those so I wait a few seconds and I then get the message "wait" then the dashed line fills up. When it has filled up to a solid line then the screen goes all black and it dies. Now I have not made any hardware changes so why does it die at that point when it got past that point 3 or 4 times in the past? Could the CD be damaged? Another possibility is the hard drive. This is relatively new and every once in a while I get a message that says"hard disk fail" during boot up and I have to hit "reset" and start over. It always starts on the second try. Another thing I need some advice on, concerning the hard drive. After the BIOS has found the hard drive and before the boot-up starts I get a message that says "No 80 conductor cable installed". What does that mean? Any advice will be greatly appreciated.
