This is the IGEL WinNET III thin client, which uses the mainboard ASI MB-5BLMP. ASI (Aquarius Systems, Inc.) seems to be Bcom now.
There's a small manual (PDF) for the MB-5BLMP.

- Ethernet: Realtek RTL8138B (10/100 Mbit), might support Boot ROM and Wake-on-LAN
- Internal power supply (25 W or 60 W, 100~240 VAC, 50/60 Hz)
Status
LinuxBIOS + FILO can boot a Linux kernel (e.g. 2.6.20) just fine.
However, as the PIRQ table in LinuxBIOS is not yet fixed (this is on my TODO list), you have to use the Linux kernel parameter irqpoll at the moment.
Building a payload
Building a LinuxBIOS image
$ cd targets $ ./buildtarget asi/mb_5blmp $ cd asi/mb_5blmp/mb_5blmp $ make
Flashing the image
$ flashrom -vw linuxbios.rom
