I've got a good boot disk w/ milo and that boots up fine. I've got a boot
disk with a generic kernel and a ramdisk. After trying many combinations of
boot lines of the form :
boot fd0:vmlinux.gz root=/dev/hda load_ramdisk=1
(or kernelname.gz) (or sda*)
also tried many different kernels ...
I have my RH6.1 cd in the drive. The kernels always unzip (#UNZIP: this is a
zipped file) and then lot's of ###### ... while unzipping, and then the
following:
...
MILO: About to reboot fd:vmlinux.gz
Hit any key to enter command mode, ESC to boot immediately
Seconds remaining: 0 23
At this point, if I hit any key, it boots milo again, if I hit ESC, it
always hangs (on all the different images I've tried).
In the alphabios, I've set the first partition (Disk 0, Partition 1) to 7Mb
and the 2nd partition (Disk 0, Partition 2) to 4084 Mb and the devices are
show below (or as stated in the alphabios install faq on alphalinux.org).

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?......
