b800.org - pastebin for B800 Video buffer screenshots, with focus on iPXE
Quick iPXE script: params && param vram ${vram} && chain http://b800.org##params && echo b800.org/${b800id} usage details

How to use with iPXE

To post vram data with iPXE use at least git version a25a16, with the below defines enabled (precompiled ipxe) #define PARAM_CMD
#define VRAM_SETTINGS
To dump current video from ipxe use chain http://b800.org/ or create your own script, the simplest form taken from the the b800.org script: params && param vram ${vram} && chain http://b800.org/?${netX/mac:hexraw}##params || echo Errorno ${errno}
isset ${b800id} && echo new id b800.org/${b800id}
Or you might want to check out the memtest example script for more advanced handling or to test: chain http://b800.org/memtest.ipxe
More ways:
# load an ipxe version with the video/vram support...
chain http://b800.org/ipxe.pxe shell
# get network up n running if needed
dhcp
# preload needed files to avoid download messages, and be able to control cursor position after output.
imgfetch http://boot.ipxe.org/memtest.0 && imgfetch -n screenshoot http://b800.org/
chain memtest.0 onepass onefail ; chain screenshoot
# This starts memtest and on exit, an screenshoot will be uploaded here.

API details

When the user-agent is iPXE, any base64 or rawhex data that matches the b800/vram syntax can be sent in a form post (iPXE params) request.
Additionally a get or post parameter public (default 0) means private, set to 1 to get it public and show on the front page.
The returned script will only try to set the b800id variable: set b800id base58key(sha1(vramdata)) so you know where to find the screenshot.
In case of error b800err should be set instead. (this will be documented more when there is known errors)

The b800id is used to get the data on b800.org/${b800id}, where the different formats that is supported is also listed. for example: b800.org/${b800id}.png
