With SATA Operation mode set to normal in the computer's BIOS settings, the RHEL4/EL4 kernel (2.6.9-42) doesn't see the hard drive even after installation. This is because the required driver was not available when ISOs were shipped. Thus the Legacy setting must be used until the driver update is installed on your system.
To change the SATA mode on the Dell Optiplex 745, enter the BIOS (F2 on boot) and go to the "Drives -> SATA Operation" screen. Make sure it is set to Legacy, not Normal, then the EL4 Linux kernel will be able to see the DVD-RW and hard drive.
To avoid a performance degradation in SATA legacy mode, add the kernel command line option:
all-generic-ide
to the kernel boot command line in /boot/grub/grub.conf after installation, and reboot the machine. Example grub.conf entry:
title Red Hat Enterprise Linux AS (2.6.9-42.0.0.0.1.ELsmp)
root (hd0,0)
kernel /vmlinuz-2.6.9-42.9.0.0.0.1.ELsmp ro root=LABEL=/ rhgb quiet all-generic-ide
initrd /initrd-2.6.9-42.0.0.0.1.ELsmp.img |
