2. Insert the driver update disk that you created on CD , DVD , floppy disk, or USB storage device
and select Yes. The installer examines the storage devices that it can detect. If there is only
one possible location that could hold a driver disk (for example, the installer detects the
presence of a floppy disk, but no other storage devices) it will automatically load any driver
updates that it finds at this location.
If the installer finds more than one location that could hold a driver update, it prompts you to
specify the location of the update. Refer to to Section 13.4, “ Specifying the location of a driver
update image file or driver update disk” .
13.3.4 . Use a boot opt ion t o specify a driver updat e image file on a net work
Choose this method only for completely new drivers
This method only works to introduce completely new drivers, not to update existing drivers.
Type linux dd=URL (where URL is the HTTP, FTP, or NFS address of a driver update image) at the
boot prompt at the start of the installation process and press Enter. The installer will retrieve the
driver update image from that address and use it during installation.
13.3.5. Select a PXE t arget t hat includes a driver updat e
1. Select network boot in your computer's BIOS or boot menu. The procedure to specify this
option varies widely among different computers. Consult your hardware documentation or the
hardware vendor for specifics relevant to your computer.
2. In the preexecution boot environment (PXE), choose the boot target that you prepared on
your PXE server. For example, if you labeled this environment r5su3-dd in the
/tftpboot/pxelinux/pxelinux.cfg/default file on your PXE server, type r5su3-dd
at the prompt and press Enter.
Refer to Section 13.2.3, “ Preparing an initial RAM disk update” and Chapter 34, PXE Network
Installations for instructions on using PXE to perform an update during installation. Note that this is an
advanced procedure — do not attempt it unless other methods of performing a driver update fail.
