Chapter 7. Updating drivers during installation on Intel and AMD systems
76
Devices already in use
You cannot use a driver update to replace drivers that the installation program has already loaded.
Instead, you must complete the installation with the drivers that the installation program loaded
and update to the new drivers after installation, or, if you need the new drivers for the installation
process, consider performing an initial RAM disk driver update — refer to
Section 7.2.3, “Preparing
an initial RAM disk update”
.
Devices with an equivalent device available
Because all devices of the same type are initialized together, you cannot update drivers for a
device if the installation program has loaded drivers for a similar device. For example, consider
a system that has two different network adapters, one of which has a driver update available.
The installation program will initialize both adapters at the same time, and therefore, you will not
be able to use this driver update. Again, complete the installation with the drivers loaded by the
installation program and update to the new drivers after installation, or use an initial RAM disk
driver update.
7.2. Preparing for a driver update during installation
If a driver update is necessary and available for your hardware, Red Hat or a trusted third party such
as the hardware vendor will provide it in the form of an image file in ISO format. Some methods of
performing a driver update require you to make the image file available to the installation program,
others require you to use the image file to make a driver update disk, and one requires you to prepare
an initial RAM disk update:
Methods that use the image file itself
• local hard drive (IDE only)
• USB storage device (for example, USB flash drive)
• network (HTTP, FTP, NFS)
Methods that use a driver update disk produced from an image file
• floppy disk
• CD (IDE only)
• DVD (IDE only)
• USB storage device (for example, USB flash drive)
Methods that use an initial RAM disk update
• PXE
Choose a method to provide the driver update, and refer to
Section 7.2.1, “Preparing to use a driver
update image file”
,
Section 7.2.2, “Preparing a driver update disk”
or
Section 7.2.3, “Preparing an initial
RAM disk update”
. Note that you can use a USB storage device either to provide an image file, or as a
driver update disk.
SATA and SCSI
During installation, you cannot provide driver updates on media that is read by a device
with a SATA or SCSI connection. For example, if the only optical drive on your system is a
DVD drive with a SATA connection, you cannot provide a driver update on CD or DVD.
