Optiplex 780 XP Home SP1 Install

- press F12 at start and chose to enter in setup settings
- set Hardisk drives on ATA => no quick blue screen
- set multicore off => no another blue screen
- set OS install on = just 256 memory active => no IRQ blue screen error

HD IDE slow transfer rate under 1mb/s Solution

This is the solution worked for me when my IDE hardisk write/read speed suddenlydropped under 1mb/s

NOTE - be careful - it's recommended you backup your Registry BEFORE you do this.
Start - Run - type regedit, OK, choose Edit - Find - type masteriddatachecksum - delete all the entities found, on the right, that have that - press F3 to search again (there is usually more than one); do the same for slaveiddatachecksum; exit regedit - reboot - your drives should be their max DMA, or the mboard's max DMA if that's less.
