Using the DiskOnChip with Linux OS

Since Lilo and the DiskOnChip firmware (i.e. doc121.exb) share the same area in RAM, the system 
will hang during boot when using an unpatched Lilo. Updating Lilo solves this problem. The existing boot 
loader needs to be updated as follows: 

# /tmp/doc-driver/plilo -i  /tmp/doc-driver/boot.b

 

This command uses the patched Lilo supplied by the TrueFFS driver and patched boot.b, and your 
default /etc/lilo.conf. Make sure that you run this command in the Linux that booted from the 
HDD. 

pLilo is actually forcing you to use smaller kernels because it allocates part of the physical memory to the 
driver. Therefore, big kernels (around 470 KB) will have a problem with pLilo (pLilo will stop with an error 
‘Kernel xxx is too big’). There are two solutions to this problem:  

1. Compile the kernel with the bzImage option (‘make bzImage’). Refer to 

/usr/doc/HOWTO/Kernel-HOWTO.gz

 for more information. 

2. Comment out all big kernels from lilo.conf (only during the installation procedure). 

M-Systems provides a patch file to Lilo sources to make pLilo. To activate the patch, you must have the 
Lilo sources available on your system. After you verify that the sources are available, type the following 
command: 

# patch -p0 < lilo-patch

 

You now have pLilo sources.
