Try booting into it with a lesser amount of ram and then ad one of the
2.4 series kernels and compile it with big mem support and some of the
other goodies in there.
Then put you extra ram in and boot it should work and if it does not
pick up all your ram ad the following line to lilo.conf
append "mem=1536000" <hope that is right just check it> ;-)
If it doesn't work mail us again or get me off list.You will not believe
what the new kernels do with a dual processor machine.
It is WOW !!!
In my experience the 2.4.3 kernel works the best on MDK 7.2
just make sure you upgrade your glibc (compile yourself)
reiser utils and modutils,and hdparm it is all covered in the HOWTO'S
Anyway have fun and let us know what the outcome is
