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.

Hardware

The IGEL WinNET III thin client.
The backpanel.
The PCB.
  • CPU: Cyrix MediaGX™ 233 MHz (a.k.a. Cyrix/NSC/AMD Geode GX1)
  • Chipset: Cyrix CS5530
  • RAM:
    • 1x S0-DIMM socket (144 pins): 32 MB
    • 1x DIMM socket (168 pins): not populated per default
  • 1x DIP32 BIOS chip
  • 1x DIP32 Disk on Chip (DoC)
  • 1x IDE (40 pin connector for ATAPI 3.5" IDE hard drives or CDROM drives)
  • VGA: integrated in the chipset, max. resolution 1280x1024 (8 bpp)
  • Super I/O chip: NSC PC87351
  • Connectors:
    • 1x PS/2 keyboard
    • 1x PS/2 mouse
    • 2x serial port (COM1, COM2)
    • 1x Parallel port
    • 2x USB (OHCI)
    • Audio: Line-in, line-out, Mic
  • Internal expansion slots:
    • 1x ISA
    • 1x PCI (shared)
  • 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

coreboot + FILO can boot a Linux kernel (e.g. 2.6.20) just fine.

However, as the PIRQ table in coreboot 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 coreboot image

See the Build HOWTO for information on how to build coreboot for this board.

Flashing the image

$ flashrom -vw coreboot.rom
