With regard to testing I've the following programmers:
+
== Wiki contributions ==
−
* (old) M4A785T-M with W25x80 DIP8(with and without coreboot) => works fine
+
My contributions to this wiki are available under the following licenses:
−
* (old) X60 with coreboot and MX25L1605 => works fine
+
* [https://creativecommons.org/licenses/by-sa/3.0/legalcode CC-BY-SA 3.0]
−
* Arduino uno and duemillanove (serprog based) => 5v only, which is problematic
+
* [https://creativecommons.org/licenses/by-sa/4.0/legalcode CC-BY-SA 4.0] or later
−
* openmoko debug board (FTDI based) => worked fine until broken in lastest svn at the time of writing,also had speed issues with some chips...
+
* [https://www.gnu.org/licenses/fdl.txt GFDL 1.3] or later
−
* (really old) 3com Nic => works fine
+
 
−
* some (really really old) reaktek cards but without chip on them.
+
== My interests ==
−
* linux_spi compatible hardwre... => works fine too so far...
+
* Easily available external flashers.
−
* An atahpt that doesn't work when adding its PCI IDs(but atahpt are known not to work according to the mailing list)
+
* BIOS->Coreboot flashing on the Libreboot compatible laptops.
−
* A very old AGP Nvidia card => works with a patch
+
* NIC flashing (to flash ipxe)
−
* A recent geforce 210 that didn't work when adding the PCI IDs
+
* GPU flashing (to flash sgabios)

This Howto will help you transform your Nvidia video card in a something that send to a serial port what would have been displayed on the screen.

The card will probably stop working as a graphic card due to the lack of VGA option rom tailored to the card.

Don't try that, it's dangerous!!!!
