I recommend sticking to the WinXP SP2 OS and formated disks. (stay away from Win98 for now as
we dont have much to offer in helps on that OS).
Below are the steps I recommend you try explicitly (start from scratch):

1. Install LB2 and install the english or international patch (I recommend the e-patch for starters as its the most tested)

2. Install LB2 DDU patch, even if you intend to
use 3DFX and not D3D graphics engine. The out-of-the-box install uses the 3DFX graphics engine, so its "optional" to install this DDU patch if you intend to stick to 3DFX.
However, if you plan on running D3D its required.
Again, I recommend installing it anyways, as Ive had success running 3DFX on 3 systems doing this and I dont know how many others Ive helped getting LB2 going on various rigs.

3. Run the new utility deposited by the DDU patch called "lb2cfg.exe", and select 3DFX.

4. Edit your CA.INI file and put this at the top:
[Backdoors]
HEAP_PERCENT=0

5. Use the "System Configuration Utility Method" which edits your BOOT.INI file and limits your RAM to 366mb. The reason I recommend this is that it doesnt install anything and is pretty easy to get right. Remember to reboot after making the changes, and to unset it after your done using it.

6. Use a GLIDE wrapper.
The older video cards you have might not need a glide wrapper, but its probably essential to have the correct 3DFX drivers that were used back then. Heres one place you might try to get 3DFX wrappers for the older cards:

Below is feedback from a guy that ran a V5 with WinXP, which is closer to what youre doing:
----------
So, problem solved on XP PRO with Voodoo 5 card:

1) Don't install glide2.dll and glide3.dll.
2) Do not put them into the windows\system32 directory!
3) Do not REPLACE your current glide2.dll or glide3.dll!

Simply extract them to the main LB2 directory!
It seems that you MUST HAVE THESE glide2.dll AND glide3.dll FILES IN THE LONGBOW DIRECTORY
--------

So you might try without the dgVoodoo glide wrapper first. If that doesnt work, then try the wrapper.

I recommend the dgVoodoo 1.40+ version (there is newer, but little testing has been done with the 1.50). Get the dgVoodoo wrapper here:

Set it up like shown below (Glide tab settings):



Then kiss the monitor and give it a go...
