Transfer the tarball to the development board using any preferred method, for

example, USB memory stick, CDROM or network transfer. Place and unpack the tarball

in the /EP805XX_release directory using the following command:

tar -xvzf <tarball name>

Tip: To mount a USB memory stick, issue the following commands:

mkdir /mnt/usb (Skip this command if directory exists)

mount -t msdosfs /dev/da0s1 /mnt/usb

A new directory structure is created under the /EP805XX_release directory that

contains all EP80579 embedded software drivers for FreeBSD. See Figure 1, “Software

Package Release Structure - FreeBSD” on page 8 for a detailed view of the directory

structure.

3.1.3 Patching the Kernel for PCI Device Recognition

Execute the following commands to patch the FreeBSD kernel:

cd /EP8057XX/Embedded/src/patches

patch -p0 < Intel_EP80579_FreeBSD_71.patch

Upon patch application, review the output. The output should contain text similar to:

Hunk #1 succeeded at 64...

This indicates that this part of the patch was applied successfully.

The following patch must be applied to ensure the correct device strings are returned

by the pciconf utility. The patch file can be found in the /EP805XX_release/Embedded/

src/patches directory. Apply the patch to the pci_vendors.patch file using the following

commands:

cd /usr/share/misc

patch -p0 < /EP805XX_release/Embedded/src/patches/pci_vendors.patch

Upon patch application, review the output. The output should contain text similar to:

Hunk #1 succeeded at 9268...

This indicates that the patch was applied successfully.
