i started to hack on a Decstation bootloader - It is currently
not booting anything but i thought of letting you know.
I put the stuff i already have at
And it is called "delo" - The Decstation Loader - It is loosly
designed like "SILO" the Sparc Loader.
I have a small application called "writeboot" which is based on
lilo and bootprep and inserts the extents to load into the
bootsector of the defined disk. This seems to work quiet well.
I succeeded to load a full kernel dumped with objcopy like this.
The second thing is the "loader" which will (when finished) use
the libe2fs to open an ext2 filesystem, load the kernel and run it.
Goal is to be able to select the kernel image to be loaded on the
prom command line like
boot 3/rz0 /boot/vmlinux root=/dev/sda5 console=ttyS2
Although i am not shure on how to select the partition/filesystem
on which to look for the kernel. Also MS-DOS Disklabel support
has to be added to be able to automatically find the partitions.
Currently i am using the first partition starting at 64 (Although
the open_ext2 currently fails :( )
