Received an Igel J series thin client (also known as the Winnet IV). Supposedly one of the smallest Socket 7 boards out there, and touted as “the ultimate retrogaming thin client” due to its integrated ESS Solo-1 instead of the usual Via embedded sound chip with SBPro legacy support...

Well, it’s not really that small. It’s actually bigger than my router-of-doom.

So what is it? When I got it the heat sink is loose and the securing clip fell off the retaining notch causing it to rattle. I actually had to pry out the plastic front bezel and release the 2 screws holding the heat sink in place. Out of curiosity I pulled the large heat sink off, and under the thermal pad lies an AMD K6-2E (embedded) 333MHz CPU, which consumes about 10w max and 2 watts idle. Unfortunately it’s not a K6-2+, so not much downclocking possibilities in setmul. The 2 PC100 SDRAM slots have 32MB DIMMs, giving it 64MB total. Subtract out 8MB for a VRAM cache used for the SiS 6326 based GPU on the SiS530 north bridge, and it’s 56MB. The SiS530 needs low density RAM so drop-in replacements off my Wyse WT8450XE (C3 Samuel 2 core based) didn’t work.
The embedded sound chip is indeed an ESS1938S Solo-1. There is a riser that can take either a 16 bit ISA card, or a PCI card...but not both. The entire device is passive cooling with no fans, and this includes the PSU as well.

So, was it a good retrogaming PC? In one word? Not really. The BIOS is gimped and missing quite a number of features. You cannot disable the onboard Realtek RTL8139C, and there are no options to control the Embedded ESS solo1 like set it up with a dedicated IRQ. DDMA doesn’t seem to work as expected so SFX support from the ESS soundchip doesn’t work as well, as, say, a Yamaha YMF724 on the Router-of-Doom. Trying to get the ESS Solo1 to work using the DOS mode essolo.sys will cause it to lock up. Using setpci to manipulate the control registers directly...works somewhat, but it’s not foolproof either. In a way it’s a choice between an embedded PCI soundcard hyped for excellent DOS compatibility (don’t seem to be the case), adding an ISA sound card (which might or might not work well) and losing the ability to l, say, have a better GPU (Voodoo2 or Savage4 PCI)
In a way you are still better off with a good retrogaming friendly laptop like a Toshiba Satellite 4280XDVD or an IBM Thinkpad T22. At least things tend to work well on those machines out of the box...
