[LinksOS CVS Commit]linksos INSTALL,NONE,1.1 COPYING,1.1,1.2

[<bg...@us...>]

Update of /cvsroot/linksos/linksos
In directory sc8-pr-cvs1:/tmp/cvs-serv19578

Modified Files:
	COPYING 
Added Files:
	INSTALL 
Log Message:

Title: Install instructions 
Changes: Added file INSTALL that contains the installation instructions

Effects: This field is redundant

t=n/a     b=none


--- NEW FILE: INSTALL ---
First obtain, compile and install grub onto your system. (Install here 
doesn't mean to use it as you bootloader but have its program files correctly 
placed on your system)
  Install grub of a floppy in the manner described below:

 1. Format a floppy disk in FAT/EXT/ any supported format:
 
        mkfs -V -t msdos /dev/fd0 <== use fd0 or fd1 as appropriate
 
 2. Mount the floppy:
 
        mount /dev/fd0 /mnt
 
 3. Create a boot directory and a grub directory on the floppy:
 
        mkdir /mnt/boot
        mkdir /mnt/boot/grub
 
 4. Copy stage1 & stage2 files to the floppy:
 
      	cp -pa /usr/local/share/grub/i386-pc/stage* /mnt/boot/grub
 
 
 5. Unmount the floppy disk:

      	umount /mnt

 6. Create /(wherever you want)/grubfd.conf file to look as follows:          

	root (fd0)                                                             
	install /boot/grub/stage1 d (fd0) (fd0)/boot/grub/stage2 0x8000 
	quit  

  7. Install GRUB on the floppy disk(this has to be done as root):
 
       grep -v ^# /(path to grubfd.conf)/grubfd.conf | grub --batch

The following is the output of the above command:
    GRUB  version x.x.xx  (640K lower / 3072K upper memory)                   
                     
                                                                              
                     
 [ Minimal BASH-like line editing is supported.  For the first word, TAB      
                     
   lists possible command completions.  Anywhere else TAB lists the possible  
                     
   completions of a device/filename. ]                                        
                     
                                                                              
                     
grub> root (fd0)                                                              
                     
 Filesystem type is fat, using whole disk                                     
                     
                                                                              
                     
grub> install /boot/grub/stage1 d (fd0) (fd0)/boot/grub/stage2 0x8000 p 
(fd0)/boot/grub/menu.lst  
                                                                              
                     
grub> quit

  8. Now in /boot/grub/ we need to create menu.lst to look as follows:

	timeout 30
	title LinksOS
	kernel /boot/kernel.elf

  9. Now make kernel.elf and copy it onto /boot/ on the floppy

 10. Whenever you make chages to the kernel, you do not have to repeat all the 
     above processes, just make the kernel and repeat step 9.

And you are Done, pop the disk into your floppy, power up and links will boot.
