Managed to boot from the CD
During logout, removed the CD and hit Enter
nothing happens
reboot to WinXP
my God!!!
missing operating sytem
unable to boot to WinXP
Pop in Knoppix CD and all my hda - lost interrupts
Used a bootable CD to DOS and no hard disk is detected
BIOS detects my hard disk though
checked the cables are secured and reboot
Finally WinXP appears but screen resolution is fixed at 800x600 4 bits
Reboot to safe mode, changed screen settings and reboot
still no good
shutdown system and boot
remove display adapter and reboot
reinstall nvidia drivers and all is well

dispaly card is 4MX440 and was using beta drivers and Knoppix detects the card
going to try booting to Knoppix without using beta drivers and see whether I can reboot to WinXP
