Query based on : LILO for RTEMS

[Joe Samuel]

Hi Rakesh,
  I had the same problem as you mentioned, but I've
managed to boot in to RTEMS using the GRUB
commandline. Here's how. 
   'You were able to create the GRUB 'boot floppy'
mentioned in that mail rt? If not you can create this
thru the commands:
  cd /usr/share/grub/i386-redhat
    Here you'll find the stage1 and stage2 files
needed. dd it to the boot floppy
 >dd if=stage1 of=/dev/fd0 bs=512 count=1
 >dd if=stage2 of=/dev/fd0 bs=512 seek=1

The grub boot disk is ready. Boot using it and in the
grub shell issue

>root (your hd partition with the rtems executive)
  At this point, you need to know how grub addresses
your devices. Hard disk 1 is termed as hd0 and
partitions are numbered from 0.(I'm talking about
grub0.91. Seems that the partition numbering in
earlier versions was different). Let your rtems
executive name be hello.exe and the partition be the
third one. Then you'll give
 
>root (hd0,2)
       Now set the kernel image using
>kernel hello.exe
 The next step is
>boot
  You're done.
best of luck
Joe
