Modern systems can accept four EIDE devices on the
hard disk controller, so there shouldn't be any problem installing both disks on
your system at the same time, even if you also have other
EIDE devices. Hard disks and CD-ROM
drives are typical EIDE devices. Floppy drives and tape
drives are usually connected to the floppy drive controller rather than to
the hard disk controller.
SCSI adapters are even more flexible and can accept
seven devices. If you're lucky (and rich) enough to have a
SCSI adapter, you probably already know this, and you
probably know which of your devices are SCSI devices!
For more information, see the SCSI How-To.
Even the oldest systems can accept two devices on the hard disk
controller, so you can still install both hard disks at the same
time. However, if you already have another device installed in addition to
your hard disk (for example, if you have both a hard disk and a
CD-ROM drive), you'll have to remove the other device
to be able to install the old hard disk and the new hard disk at the same
time.
You must configure the disks as master or
slave by installing the disks' jumpers as
appropriate. You'll often find configuration information on the disks
themselves; if not, consult the manuals or the disks'
manufacturers.
You must also inform the BIOS of the disks'
presence and of their geometry. Usually, you enter
the BIOS setup program by pressing a key during the
system boot-up. Here's what to do for some common
BIOSes:
- Acer notebooks
F2 key during Power-On Self-Test
(POST)
- American Megatrends (AMI)
Del key during Power-On
Self-Test
- Award
Del, or
Ctrl-Alt-Esc
- Compaq
F10 key after the square appears in
the top right corner of the screen during
boot-up
- Dell
Ctrl-Alt-Enter
- DTK
Esc key during Power-On Self-Test
- Hewlett-Packard Pavilion
F1 key during HP blue splash screen
- IBM Aptiva 535
F1 while the square with the wavy
lines is displayed in the upper right corner during power-on
[1]
- IBM PS/2
Ctrl-Alt-Del, then Ctrl-Alt-Ins when the cursor is in the top right corner
- Mr. BIOS
Ctrl-Alt-S during Power-On Self-Test
- Packard Bell
For some models, F1 or
F2 key during Power-On Self-Test
- Phoenix
Ctrl-Alt-Esc, Ctrl-Alt-S, or Ctrl-Alt-Enter
Many older systems require an Installation or
Reference Disk.
We're interested in receiving information on other BIOSes to add them
to this list.Reboot the system and login as root. If you use the
su command to become the user root, use su -, with the hyphen option.
