Binary package “loadlin” in ubuntu focal
loader (running under DOS) for LINUX kernel images
LOADLIN-1.6 is highly adaptable to different DOS configurations, and now
has very few loading restrictions. It makes use of extended memory and
also can load big kernels (bzImages) and ramdisk images (initrd)
directly high.
.
LOADLIN also can load out of Virtual-86 mode (which is normal when
using EMS drivers) if a VCPI server is present.
.
The loadlin package also includes the freeramdisk program, which can
return memory to the system when a ramdisk is no longer needed.
