Or use netconsole. (similar to serial console but over the network :))

I'm running a seagate 250GB SATA drive as the main boot drive of the

instead to use the new hard disk:

dmidecode shows the motherboard Version: ASUS A7N266-VM ACPI BIOS Rev

Upgrading to the kernel-2.6.17-1.2139_FC5 release caused the system to
completely fail to continue booting; I got a long string of error
messages that never get logged because the boot process past the grub
bootloader never gets that far.
commenting out the new kernel (or otherwise choosing the previous
kernel-2.6.16-1.2133_FC5 release) returns the boot process to normal and
I am able to get in just fine again. Rushed this one out, did we? :-)
My experience is just the opposite. 2.6.17 is the first kernel I can boot
since 2.6.13.
Anyway, you need to log those kernel messages. Without them, there's little
to go on.
Go get yourself an RS-232 null modem adapter, and connect the serial port on
this machine to a serial port on another box. Run minicom on the other box,
set it to 9600,8N1, and begin capturing.
Now, boot with "console=ttyS0,9600 console=tty0", and you'll get to capture
all the kernel errors, in all their glory.
