is there in any information on the site about setting up a duel boot with windows.. I want to try HAIKU but I still need access to my windows app's
Not on the site but I can give quick information.
Be sure you can access your hard drive with Haiku Alpha CD before trying to install it.
Use Gparted LiveCD to re-size (Windows) - make partition smaller. Create new partition for Haiku in empty space. Careful because Gparted can delete partitions too.
Re-size Windows to smaller size and make it first partition ( re-size from the end not the front ). Create new partition 2 in empty space. You may have to format it fat32 - I believe un-formatted may cause issue. Gparted is great for partitions and resizing.
Insert Haiku Alpha CD. Follow instructions here:
Be sure to install Haiku to the right partition. You may want to backup your important Windows files onto flash drive.
You'll also require a boot manager, Haiku's bootman should work. This allows you to choose which OS, Windows or Haiku, to boot. Grub & Lilo can be used if you have Linux installed. Bootman should install but sometimes there can be an issue with it. There are other 3rd party boot managers that can be used too but you'll have to find them yourself (if you can't install bootman).
If all works right then great but you should still have a LiveCD ( Haiku & Linux ) handy because you may mess something up and have trouble booting off the hard drive until you fix it.
All of this is easy to do but you have to be careful not to delete your Windows partition, just re-size it. Go slow and you should be fine.
