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!

This page describes how to use coreboot on the BCOM WinNET P680 motherboard. This board is used in the HP/Neoware e140 (aka CA22) and Igel 4210LX Winestra thin clients.

This page is a work in progress.

Status

Works somewhat. See known problems below. Work is in progress to fix these issues.

Known problems

  • L1/L2 cache are running extremely slow, 11-12MB/s per Memtest86+. As a result, loading kernel/initrd is very slow
  • irq_tables.c from the factory BIOS does not work. The epia-cn table has been substituted, but it has problems too (Ethernet doesn't work right: 50% packet loss.). A workaround is to use the kernel parameter "irqpoll"
  • Boot log shows INT15 handler isn't working
  • hda in Linux is hde in FILO

Some of this may be corrected by coreboot, but some is a chipset limitation. More should be known when coreboot is working again.
