This page describes how to use coreboot on the Jetway J7F2 series mainboards.

This page is a work in progress.

[edit] Status

This board works with target/jetway/j7f24, except that it needs rev 3566 of src/southbridge/via/vt8237r.

[edit] Known problems

  • hda in Linux is hde in FILO
  • loading kernel/initrd is very slow
  • irq_tables.c from the factory BIOS does not work. The epia-cn table can be substituted.
  • VGA console flickers badly under intense disk activity, such as dd if=/dev/hda of=/dev/hdc
  • Current code is broken (doesn't compile). Pull rev 3566 of src/southbridge/via/vt8237r
  • Network card loses MAC address on power-loss, preventing the Linux via-rhine driver from activating it. Latest code in src/southbridge/via/vt8237r/ may fix this, at least allowing hard-coding the MAC address into the rom. However, it is also stored somewhere else on the system (not in the factory rom) so it should be readable from somewhere.
