I have tweaked this installation a bit to include functional Soundblaster emulation when booted into a native DOS environment.  You are now greeted with a boot menu upon powering up giving you the option to boot into Windows or into DOS.

This listing is for a re-purposed Wyse Vx0L Mini PC with the following specs:

-Windows 98 (SE) or DOS boot option
-800 MHZ VIA c7 CPU (BIOS configurable from 400 to 800 MHZ in 100 MHZ increments)
-512 MB DDR2 RAM clocked at 533 MHZ
-16 GB Solid State Hard drive (44-pin IDE vertical DOM)
-CN700 Unichrome Pro graphics w/64 MB shared RAM (BIOS configurable at 16, 32, or 64 MB)
-DVI output with support for VGA or dual-monitor VGA/DVI with proper adapter and/or cable
-VT8237 AC97 sound with Windows 98 support for Soundblaster emulation and General MIDI music
-Soundblaster emulation (automatically configured) in DOS (port 220, IRQ 7, DMA 1)
-VT6102 Rhine-II Ethernet adapter
-1 front and 2 rear USB 2.0 ports
-1 Parallel Port
-1 Serial Port
-Dedicated PS/2 keyboard and mouse ports
-Windows 98SE Installed with 100% device driver compatibility
-Includes Power adapter, power cord, and DVI-to-VGA adapter

Windows 98 SE configuration:
-All hardware drivers installed
-Daemon Tools v3.47 installed for mounting ISO's as virtual CD drives
-SeaMonkey 1.1.19 web browser
-Hard drive changed from PIO to DMA transfer mode
-TCP Optimizer patch installed to increase network throughput to much closer to broadband speeds
-Universial Native USB disk driver (supports most smaller flash drives and external CD drives)
-DirectX 9.0c

Some of the BIOS Options:
-Set the boot order
-Set the CPU multiplier from 4x to 8x in 1x increments (400 to 800 MHZ speed) (or up to 12x on faster motherboard)
-Disable the L1/L2 cache
-Set the shared video RAM at 16mb, 32mb, or 64mb
-Manage IRQ settings (IRQ 3 to 15)
-Disable various onboard devices

Note about Optical Drives:
This machine will support most external USB optical drives (CD/DVD) in both Windows 98 and XP, but such a drive is NOT INCLUDED.  The references you see to external drives in the photo/screenshots are for the virtual drive that installs as part of Daemon Tools.

Note about DOS:
Compatibility is hit-or-miss, but with recent findings regarding getting Soundblaster emulation working on various AC97 sound chips, I figured I would include that on this build since it does work.  Duke Nukem 3D (all the way up to 800x600 resolution) and Wolfenstein 3D both play flawlessly with functional audio.
