• Deployment Solution

Issue/Introduction

HP* dc7900 desktops that have Intel* based chipsets will not boot into Linux environment.

Cause

• hardware conflict during boot of linux automation environment
• nic drivers need to be compiled
• environment variables need to be set in the pxelinux.cfg
• ICH7 - ICH9 SATA controller

Resolution

1. There is a hardware conflict during the uncompressing of the root.gz. To get around that follow KB article 28717

2. The intel nic has a new chipset. Please download the new driver for Linux automation. ( this driver is for kernel version 2.6.18)

          For a how to on compiling drivers for Linux environment follow KB article 36079

3. An updated ahci.ko must be added to your linux environment.(see attachment ahci.zip)

AUTOMATION/NETWORK BOOTDISK:

1. If making a bootdisk or usb bootdrive make same changes to the syslinux file. The syslinux file should look like:

 

default linux
label linux
        kernel linux
        append initrd=rootfs.gz root=/dev/ram0 rw ramdisk_size=32768 quiet pci=conf1

 

 

NOTES:

If the e1000.ko doesn't work use the e1000e.ko. Do not load both due to a driver confict if both drivers are include in the automation environment.

In Linux Hardware Independent Imaging is not supported.
