Add iPXE entry to Grub

Just install the ipxe package (apt install ipxe) and run sudo update-grub afterwards.

OpenWrt on HP Microserver Gen8

This was done when the server already had a working debian in its own partition. Can be done also in a new/empty disk using a live install disk.

• Download required files:
• rootfs image (e.g. https://downloads.openwrt.org/releases/19.07.5/targets/x86/64/openwrt-19.07.5-x86-64-rootfs-ext4.img.gz).
• kernel (e.g. https://downloads.openwrt.org/releases/19.07.5/targets/x86/64/openwrt-19.07.5-x86-64-vmlinuz).
• Network driver: kmod-libphy and kmod-tg3 (https://downloads.openwrt.org/releases/19.07.5/targets/x86/64/packages/kmod-libphy_4.14.209-1_x86_64.ipk and https://downloads.openwrt.org/releases/19.07.5/targets/x86/64/packages/kmod-tg3_4.14.209-1_x86_64.ipk).
• Prepare a partition for OpenWrt
• Copy image to hard disk partition with dd or similar tool.
• Copy kernel to /boot.
• Copy both ipk files for the network driver to /tmp.
• Install grub2 to the disk if not present already.
• Write a grub entry for OpenWrt, e.g. (modify partition location/id as needed):

menuentry 'OpenWrt 19.07.5 (on /dev/sdc2)' --class openwrt --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-simple-57f8f4bc-abf4-655f-bf67-946fc0f9f25b' {
    insmod part_msdos
    insmod ext2
    set root='hd2,msdos2'
    if [ x$feature_platform_search_hint = xy ]; then
        search --no-floppy --fs-uuid --set=root --hint-bios=hd2,msdos2 --hint-efi=hd2,msdos2 --hint-baremetal=ahci2,msdos2  57f8f4bc-abf4-655f-bf67-946fc0f9f25b
    else
        search --no-floppy --fs-uuid --set=root 57f8f4bc-abf4-655f-bf67-946fc0f9f25b
    fi
    linux /boot/vmlinuz root=/dev/sdc2
}

• Update-grub
• Boot
• opkg install /tmp/kmod-libphy... and opkg install /tmp/kmod-tg3
• Configure as needed
• Once you have internet connection consider install additional packages (e.g. nano, luci-admin-full).

Rufus - Create bootable USB drives the easy way

I normally use UNetbootin for my bootable USB drives but Rufus worked great when I used it recently.

config.txt for (Raspberry PI) + (HDMI to VGA Video + Audio Adapter)

Here's our known-good /boot/config.txt which will set the resolution to 800x600 and enable the audio out of the adapter. we have a couple other resolution options documented as well!:

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=87
# Put your VGA monitor resolution below
# hdmi_cvt =       
# width        width in pixels
# height       height in pixels
# framerate    framerate in Hz
# aspect       aspect ratio 1=4:3, 2=14:9, 3=16:9, 4=5:4, 5=16:10, 6=15:9
# margins      0=margins disabled, 1=margins enabled
# interlace    0=progressive, 1=interlaced
# rb           0=normal, 1=reduced blanking

# For example, 800x600 @ 60 Hz
hdmi_cvt=800 600 60 1 0 0 1
# or maybe 800x480 @ 60 Hz
#hdmi_cvt=800 480 60 6 0 0 1
# or, 1024 x 768 @ 50 Hz
#hdmi_cvt=1024 768 60 1 0 0 1
# or if you're not sure, nothing beats 640x480
#hdmi_cvt=640 460 60 1 0 0 1

# see http://www.raspberrypi.org/forum/viewtopic.php?f=29&t=24679

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
###############################################################
### THIS LINE IS WHAT ENABLES THE AUDIO OUT OF THE ADAPTER! ###
hdmi_drive=2
###############################################################

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# for more options see http://elinux.org/RPi_config.txt
