To boot a kernel on the Point 510, you most probably have to compile one
of your own, as you need EISA bus support. Furthermore, make sure to enable
PCMCIA and APM support.
If may want to take a loot at my kernel configuration
as a starting point. You can also download a complete kernel (2.4.18)
here, but you have to copy the required modules
for you PCMCIA cards to /lib/modules/2.4.18/pcmcia on your own...
This is work and progress!
Both files contain stupid settings and may lack some things you need - so there is
NO WARRANTY that these files won't fry your 510!.
When you have your kernel image ready, you might need to pass the "mem" parameter at
boot time to tell the kernel how much memory is installed to your unit. In my case,
I have to set mem=32mb.
If you don't know how to set boot parameters, take a look at your loadlin.exe
documentation, do a man lilo.conf etc. => RTFM
