For Warp 3 to boot (and Warp 4 without LVM if I recall), your boot partition needs to be within the first 1024 cylinders of the hard disk (or something like that). What this means is if you try and make your whole 8 Gig hard disk into a single partition, you're unlikely to ever get it to boot.The answer is to create a smaller partition, and a second partition to use for data. Fortunately Warp 3 is quite small anyways - it installs in less then 100 MB.
So my suggestion is to create a primary partition of less then 2 gigs (maybe try 1 Gig, that'll be more then enough) for installing OS/2 on, and do the rest of the drive as an extended logical.
Second thing - if you're using the original boot disks, you'll need to update them. Grab:
ftp://service.boulder.ibm.com/ps/products/os2/os2ddpak_cur/idedasd.exe
Unzip that file into a directory and you'll find the following files:
DASD16 DMD
DASD32 DMD
IBM1S506 ADD
IBM1S506 SYM
IBMATAPI FLT
IBMIDECD FLT
IDE16 DDP
IDE32 DDP
OS2CDROM DMD
README TXT
Out of these, you can delete the following files:
DASD32.DMD
IDE16.DDP
IDE32.DDP
Then rename DASD16.DMD to OS2DASD.DMD
You'll probably need to create a new Disk 1, and get more space on it. For directions on how to do that, check:

If you want to use the Danis driver, grab the latest DANIS506.ADD from:
http://hobbes.nmsu.edu/cgi-bin/h-search?key=danis506&pushbutton=Search
And you'll need to replace the line :
basedev=ibm1s506.add
with:
basedev=danis506.add
in your config.sys (after having copied that file to your drive)
For fdisk, you may need an updated version of FDISK.COM to get your partitioning to work. You can find a more updated copy on Fixpak 40's disk 7:
ftp://service.boulder.ibm.com/ps/products/os2/rsu/xr_w040/xr_w0407.zip
Unzip that file, and you'll need to use the OS/2 unpack.exe command to unpack the fdisk.co_
Hope this helps
