DIY ViDock PCI Bridge Automated Configuration Script
=====================================================
1/ Designed to allow connecting an external video card to a notebook. This
will configure the hosting bridge using DOS utilities to enable an I/O and
Memory window to accomodate the underlying graphics card. Without this you'll
see "error 12: cannot allocate resources" errors in XP/Win7.  This should
ideally be sorted by your BIOS or Windows, though in at least the 2510P's
and DV2000's case it isn't.

grub4dos is then used to chainload your XP/Win7/Linux bootloader.

2/ Example x2-conf.bat can assist in identifying identifying if you may 
have a x2 capable system, as well as hardsetting x2 or x4 mode.

Instructions
============

1/ Create a bootable USB or floppy drive. Copy these files OR the write the
DIYVDock-conf.img to your USB/floppy using winimage, rawrite of Linux'
'dd if=DIYVDock-conf.img of=/dev/xxx'.

2/ Use the two tested examples to create your own system specific batch file.

* 2510P.BAT : HP 2510P+PM3N. Uses whitelst.bat to undo HP Whitelisting 
* DV2000.BAT: HP Pavilion DV2000+EC2C.  

3/ Now can use your USB or floppy to allow desktop video graphics to work.  

4/ OR, if you already have grub installed, create an image of your floppy
with 'dd if=/dev/xxx of=/boot/VIDVDock-conf.img'. Add an entry in
/boot/grub/menu.lst to boot off this floppy image. This boots a ramdisk 
and is recommended for it's faster bootup than using a USB stick. 

   title           DIY ViDock PCI Bridge Configuration   
   root            (hd0,0)
   kernel          /boot/grub/memdisk
   initrd          (hd0,0)/boot/DIYVDock-conf.img
   quiet

Can edit the bootimage in Linux with:

   losetup /dev/loop0 /boot/DIYVDOCK-conf.img
   mount   /dev/loop0 -o loop /media/floppy-image
   cd /media/floppy-image
   [ edit the files using vi ]

You'll need to grab syslinux and copy memdisk to make this work.

$ apt-get install syslinux
$ cp /usr/lib/syslinux/memdisk /boot/grub/memdisk


Tools used
==========
- pt.exe as part of peridos (http://stashbox.org/657491/peridos.zip).
Everything that Baredit can do in Windows, pt.exe can do in DOS, plus
it can also write to I/O ports too. This is incredibly useful for our
purposes. It can read/write/save/dump PCI Registers/IO and 32-bit memory space.
Though for individual PCI Device Configuration space modification I used
setpci instead, since it's also supplied with Linux.

- grub4dos to allow chainloading from DOS to XP/Vista/Win7/Linux.

- setpci/lspci, pcitool to query and modify PCI Configuration Registers. 
pcitool is a DOS component delivered with PCIScope, Professional PCI probing
utilities. Useful to capture all the configuration space (pcitool /DB:all) 
then import it in PCIScope for Windows for analysis or comparison.

- atiflash to scan the bus for an ATI video card.

- Freedos provides a DOS environment. edit and choice from a DOS bootdisk.

- arj/xmsdsk (ramdisk) for whitelist file management [if you need it]. The 1MB
snapshot file used to overcome whitelisting compresses to 2k with arj and
decompresses to a fast ramdisk.
