How to implant in GRUB 1.96 and GRUB 2.00+ kernel command from GRUB 0.97?

How to implant in GRUB 1.96 and GRUB 2.00+ kernel command from GRUB 0.97?

[Stojsavljevic, Zoran]

Hello,

I have old 32bit GRUB version 0.97 installed long time ago on HDD. I am adding to it 32bit kernels for testing with the command: linux (hd0, 1)/images/bzImage_x.y.z [options] ...<cr>

I was able to add and boot standalone Bare Metal environment (around 60KB in size) using the following two lines:
kernel (hd0,1)/images/kernel<cr>
boot<cr>

This does boot my CPUs to use cases I would like them to execute.

I tried the same for GRUB version 1.96, but this does not work anymore! Did not try it for GRUB 2.00+...

The question is: what are the substitutes for commands (in GRUB 0.97):  kernel (hd0,1)/images/kernel<cr> boot<cr>
[1] For GRUB 1.96?
[2] For GRUB 2.00+?

Thank you in advance,
Zoran

RE: How to implant in GRUB 1.96 and GRUB 2.00+ kernel command from GRUB 0.97?

Njet, Andrey...

Command is:
mulitiboot (hd0,1)/images/kernel
Boot

I found the grub 1.98 manual, and looked into it. My guess is that multiboot does work for 1.9x+ and 2.00+. For 0.9x+ it is kernel keyword.

I'll subscribe to help-grub.

Thank you,
Zoran

linux16 (hd0,2)/images/kernel
boot

Please post further questions to help-grub, they are off-topic on development list.

I'm pretty sure nobody cares about 1.96 any more; it was a five-year-old
version of a development branch.  I'm certainly not going to try to go
back and work out what would have worked with it.  Sorry.  You could
always try going with the instructions for 2.00 if you're desperate, but
please just upgrade instead.

GRUB Legacy's "kernel" command was a magic thing that tried to detect
the kernel type and implement appropriate loading.  In GRUB 2, there's
instead a loader command for each kernel type: "linux", "multiboot2",
"knetbsd", etc.

Given that your kernel worked with GRUB 0.97, my guesses would be that
either it's a Multiboot 1 kernel (since GRUB Legacy didn't support
Multiboot 2), in which case you want the "multiboot" command; or it was
relying on the 16-bit Linux boot protocol, in which case you want the
"linux16" command.

The other thing to bear in mind is that GRUB 2 numbers partitions
starting at 1, not 0, so (hd0,1) in GRUB Legacy typically becomes
(hd0,2) in GRUB 2.

So, putting that all together, my guess is that a menu entry declaration
for your kernel in GRUB 2 would be something like this:

  menuentry "My bare-metal environment" {
    multiboot (hd0,2)/images/kernel
  }

... or, if you just want to type directly at the GRUB shell:

  multiboot (hd0,2)/images/kernel
  boot

[Stojsavljevic, Zoran]

Hello Colin,

Yes, I discovered it myself. I somehow found one HDD with 32bit GRUB... Version 1.96. Lazy to pull and install from grub git the latest snapshot, since I am busy with many other stuff (and I should do that, this is the proper way).

But anyway, thank you for the tip. For both versions (1.96 and 2.00+) exactly what you wrote there:

multiboot (hd0,1)/images/kernel
boot

Best Regards,
Zoran
