Ok first off you really can't stack the packages
you need to do them one at a time. Tony was having a
similar problem if you will read down 2 messages ago
if you want good popping ratio the trick is, lay the kernels
flat and even. this should fix your problem

hmmmmm
I had compiled my kernel with gcc and linked it with
ld
gcc -ffreestanding -c -o kernel.o kernel.c
ld -Ttext 0x10000 --oformat binary -o kernel.bin kernel.o
where can i switch the memory model to flat memory
