I discovered that by making a 4M image instead of a 16M image, I could 
get everything to work.

I also tried gzipping the 16M ramdisk kernel, and it still failed. The 
gzipped kernel was around 2M. My guess at this point is that there is 
not enough RAM for the kernel and the ramdisk to run in. So what is a 
good way to get a detailed report as to how the RAM is being used? The 
dmesg output below indicates that a typical 1.6.0 kernel will have about 
24M free. This sounds like it should be enough for the 16M ramdisk, plus 
any overhead.

For Perry, below is the dmesg output. I don't even see the DiskOnChip in 
there. If I recall, it is only active if the primary IDE drive is not 
present. Since I have a 2.5" IDE drive plugged in, I can't see the DOC. 
I'm going to scrounge for a floppy drive, so I can boot a kernel and see 
if the DOC shows up in the dmesg output. For reference, this is a AAEON 
PCM-5894 single board computer. I got it about 5 years ago when I went 
to a training class. The specsheet is here.
ftp://data.aaeon.com.tw/download/MANUAL/PCM-5894Manual.pdf

The DOC should look like the primary master drive and so I would guess 
that it would show up as wd0. But I need to unplug my IDE drive first. 
But since I don't have a floppy plugged in, I would have no way to boot 
the machine.

Again, thanks for all the help.

Brian
