RE: can't install image for miata ...

[Larry Snyder <larrys lexis-nexis com>]

Let's look at what works first:
You've got a good boot disk that pulls milo in.  That's the first step,
stick with it.

Next step is to load a working kernel.  IIRC, milo can handle both
ext2 and msdos filesystems.  Try copying a kernel image to a 
dos-formatted disk with the copy command under nt.  Then boot milo,
stick the new kernel floppy in, and tell it:
boot fd0:kernelname.gz (where kernelname.gz=your copied image).
At this point it should gripe mightily about mounting the root
partition.  That's fine.  If it says it can't load the kernel, it
may well be a milo problem.  Else, continue...

Once you've gotten this far, you should be able to cold-boot back into
milo, put your kernel disk back in, and at the milo prompt 
say boot fd0:kernelname.gz root=/dev/hda.

A full description of your hardware would be helpful.  Also, do you
have a partition roughly 2xmemory in size for swap?  axp kernels
normally expect the root partition to be /dev/sda2, so you'd want
your disk to have
sda1=small loader ptn
sda2=big root ptn
sda3=2xram swap

...and why the sda5?......
HTH,
-ls-
