LS-120 install

[Lauri Laupmaa]

Hi

I'm trying to install FreeBSD 5.0 RELEASE from ordinary kern.flp and 
mfsroot floppies, which work flawlessly on fd0 drive, but not on a 
machine with ATAPI LS-120 drive.
After spinning wheel some times, it falls out and claims it cannot find 
neither /boot/loader nor /kernel I tried to put different devices (i.e. 
ad0(1,a)/boot/loader, wfd0 and so on) to boot: prompt, but to no avail.

Is there a way?
TIA

L.
