old bios that does not support lba-12 will have problems,
thus the dumb work around to put /boot under the 1024 cyliner limit

another equally dumb way is to boot off floppy 

another silly way out is to go to your local surplus place and buy a 20GB
disk for $20 to install linux onto it and you're now "fixed"

the 1024cylinder boundry is at 504MB limit

32MB is not the issue

more bios problems

kernel chews up 50m - 100mb depending on what you do to it
