Okey Pokey, so I did a bit more reasearch and now understand how patches work, they're just a file that lists all the differences between some standard source code and a modified version, the patch command line utility is able to decipher the diff file and modify the various source files for you. I also found out about how patches are designed for a specific version of code and so you need to find the appropriate patch for your specific code (what an educational process!). To make a long story short, I decided it was a much better idea to download the source for the latest stable kernel (2.6.11.7). I ran xconfig, scrolled to the IDE/ATAPI options and found support for the sis5513 chipset was listed, so now I'm able to make an sis5513 compatable kernel (and a nice up to date one at that) - much easier than faffing around looking for the appropriate patch, why didn't I think of it earlier. As long as I can work out how to make a bootdisk out of it, everything should be sweet.

Thanks for the help guys

Ok, so I made a custom kernel from the 2.6.11.7 kernel source and copied it over to the bootdisk. When booting, It loads the kernel just fine, then starts scrolling all that jibberish past the screen, but stops with an error...

NET: Registered protocol family 17
VFS: Cannot open root device "<NULL>" or unknown-block(3,4)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,4)
<7>spurious 8259A interrupt: IRQ7.

I'm not sure what this is, but I get the feeling that it's something to do with the Ramdisk not setting up properly? I tried telling it...

ramdisk root=/dev/fd0

when the bootdisk first asks for parameters to pass to the kernel, but I get a similar error to above...

NET: Registered protocol family 17
VFS: Cannot open root device "fd0u1440" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
<7>spurious 8259A interrupt: IRQ7.

I also looked at the "config" file on the bootdisk and found that the bootdisk's kernel already has support for the sis5513 ide controller enables, which make's me wonder why the stock bootdisk was panicing?

Is anyone able to help me? Thanks in advance,

Francis

Ok, I drug the old Premio out from under the bed and gave it a whirl using the Slackware 10.1 bare.i bootdisks. With that disk, without any changes except I changed it to output to a serial console so I could copy/paste the below, as expected, I got the below kernel panic:
Code:

Code:  Bad EIP value.
 <0>Kernel panic: Attempted to kill init!
So, I recompiled the bare.i kernel disabling the compiled in SIS5513 driver, ie I changed it to load as a module. Here's how I built the kernel using the config from the bare.i bootdisk.
Code:
tar jxvf linux-2.4.29.tar.bz2
cd linux-2.4.29
make mrproper
mount /mnt/floppy
cp /mnt/floppy/config .config
make menuconfig
As stated above, all I changed was this and exited the kernel configuration:
Code:
ATA/IDE/MFM/RLL support  --->
  IDE, ATA and ATAPI Block devices  --->
    <M>     SiS5513 chipset support
Then I built the kernel:
Code:
make dep
make bzImage
cp arch/i386/boot/bzImage /mnt/floppy/vmlinuz
cp System.map /mnt/floppy/
cp .config /mnt/floppy/config
umount /mnt/floppy
That should get you past the bug. The problem is the inclusion of the sis5513 in the kernel, not the exclusion of. Also with the bootdisk, if you type anything at the boot: prompt, then you'll need to re-add the root=x option and some others, because the syslinux.cfg file on it is setup in such a way that those options don't get passed if you speficify others. This is likely the reason for your problem in your last post. In other words, if you want to change or add boot options, then pas the entire line modified as needed, like so:
Code:
vmlinuz ramdisk_size=7000 root=/dev/fd0u1440 vga=normal rw SLACK_KERNEL=bare.i
Else you can use "ramdisk" instead of "vmlinux" and all the above will be automatically appended.

Now, that should get you booted to this prompt:
Code:
VFS: Insert root floppy and press ENTER
Here it is requesting the install.1 disk. But, always a but. :) If you want to use the SIS5513 driver during the install, you'll need to add it to that image as well. It may work without it. It worked fine accessing my hard disks (one at primary master, the other at secondary master) but wouldn't work with the CDROM. But neither would the sis5513 driver, so the drive may be shot, don't recall. But anyway, it's no big deal to add it if you want. To do that, first build the modules, from the kernel source tree run:
Code:
make modules
Now we need to install them, but we don't want to trample on any 2.4.29 kernel we already have installed, so install them like this:
Code:
make INSTALL_MOD_PATH=/lib/modules/custom modules_install
That will install the modules as well as setup them up, in /lib/modules/custom. You can package that up in a tarball and use it instead of the Slackware modules package if you want. The SIS5513 module is NOT in Slackware's default package, so you'll either need to package these and install them or rebuild your kernel once you're up and running. You could also probably just grab the /lib/modules/custom/lib/modules/2.4.29/kernel/drivers/ide/pci/sis5513.o module, add it to the modules Slackware installs, and rerun depmod after your up and running. That's only if you're using a Slackware 10.1 system to build these on though. Simpliest way is probably to rebuild the kernel once up and going. Anyway, I'll show you how to add it to the disk.

Grab the install.1 file, decompress and mount it:
Code:
gunzip -S .1 install.1
mkdir /mnt/loop
mount -o loop install /mnt/loop
Now copy the module and module.dep to it:
Code:
mkdir -p /mnt/loop/lib/modules/2.4.29/kernel/drivers/ide/pci
cp /lib/modules/custom/lib/modules/2.4.29/kernel/drivers/ide/pci/sis5513.o > /mnt/loop/lib/modules/2.4.29/kernel/drivers/ide/pci/
cp /lib/modules/custom/lib/modules/2.4.29/modules.dep /mnt/loop/lib/modules/2.4.29/
umount /mnt/loop
gzip -S .1 install
Now write the new image to a disk, as well as install.2:
Code:
cat install.1 > /dev/fd0
--- Insert a 3rd disk ---
cat install.2 > /dev/fd0
If you want to use that module during the install, then just do a "modprobe sis5513" before entering "setup". Anyway, as I said above using the sis5513 driver as a module instead of compiled into the kernel eliminated the kernel panic. I still wasn't able to access the CDROM though, but it has always been troublesome and may have finally keeled over. I don't use the sis5513 driver at all, module or otherwise, and haven't had any problems except for the CDROM. Anyway, goodluck.

Ok, so I copied the config file to my linux directory and made a new kernel with the SIS5513 support compiled as a module and I copied it to my floppy, but when I try to copy the System.map file, I get this error..

root@SlackBox:/usr/src/linux# cp System.map /mnt/floppy/
cp: cannot create regular file `/mnt/floppy/System.map': No such file or directory

or

root@SlackBox:/usr/src/linux# cp System.map /mnt/floppy/system.map
cp: cannot create regular file `/mnt/floppy/system.map': No such file or directory

..which I can't really understand since the old system.map file IS on my floppy and it should just write over it, but anyway, I use the -f flag to force it to overwrite the existing file..

root@SlackBox:/usr/src/linux# cp -f System.map /mnt/floppy/system.map
cp: writing `/mnt/floppy/system.map': No space left on device

..but it seems that the file is too big

So what do I do? I noticed on the original boot floppy that there is a system.map file aswell as a system~1.gz file which seems to be the same kind of thing as system.map, but compressed, but what would be the point in having both compressed and uncompressed versions of the same file?

Also I've noticed that in my /usr/src/linux directory there is a System.map file, but the version on the floppy is named system.map i.e. with a lower case "s", is this right?
