The 2.4.20-2 kernel boots up on the Dell Inspiron 4100 Laptop. The laptop is
running BIOS A11 and has all the power management turned off. However, when a
hdparm command is encountered in /etc/rc.local. The machine crashes. Without the
hdparm command the machine finishes booting and it usable. The command is the
