IPXE
The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
iPXE is a tool for loading an operating system over a network. It is a fork of GPXE.
Like GPXE uses legacy BIOS callbacks, and it works well with SeaBIOS. See GPXE.
Building and Running in seaBIOS howto
Here are the goals of this howto:
- fits in 128k for easier building process
- boot over an ath9k WiFi over an open/unencrypted wifi to an image that resides on the internet...
Building
Identify your wireless network card:
# lspci [...] 03:06.0 Network controller: Atheros Communications Inc. AR922X Wireless Network Adapter (rev 01)
Identify its PCI IDs:
# lspci -s 03:06.0 -nnn 03:06.0 Network controller [0280]: Atheros Communications Inc. AR922X Wireless Network Adapter [168c:0029] (rev 01)
get ipxe:
git clone git://git.ipxe.org/ipxe.git cd ipxe/src/
Copy the following into
