Grub 0.93 grub-2003-01-08-doc.patch DOC2000 trouble

[Jeb Campbell]

Problem with MBR -- steps to get there:

1)patch grub-0.93 with grub-2003-01-08-doc.patch:
cd grub-0.93
patch -p1 < ../grub-2003-01-08-doc.patch
export WANT_AUTOMAKE_1_5=1 WANT_AUTOCONF_2_5=1
aclocal && automake --add-missing && autoconf
./configure --exec-prefix=/ \
         --disable-auto-linux-mem-opt \
         --enable-diskonchip-2000 \
         --enable-diskonchip-ctrlbypass \
         --enable-rtl8139

This patches and compiles fine and grub_firmware is 120K

2) boot dos
use v4.2 DUPDATE /win:d600 /s:DOC42.EXB and power cycle

3) boot dos to format 48M DOC2000 and load grub_firmware
use v5.1 DFORMAT /win:d600 /BDKF0:grub_fir /BDKL0:160000
formats ok and then power cylcle

4) use grub to boot linux off hard drive (2.4.19 with cvs mtd nftlcore 
1.87 and nftlmount 1.31)
fdisk -l /dev/nftla
shows the fat16 partion
mke2fs -m 0 /dev/nftla1 (no root reserve)
and it mounts fine

But when I unplug the hd, grub fails on invalid MBR on the DOC2000-48M
I can netboot and get a kernel from tftp and boot the chip fine.

But the strangest thing is grub will get the menu.lst from the DOC on 
the first partition!  But then error out when trying to boot/load the 
kernel.

Any help would be appreciated.  I don't know if I need to take out some 
of the error checking for the MBR?  Anyway I would like to use grub-0.93 
because the realtek netboot driver works (and 0.92 will not).

Thanks again,

Jeb Campbell

What is this option for?

What is the error message?  I believe there can be a conflict between the 
"netdisk" and "diskonchip" default drive selection in stage2/asm.S.

Is this the same error as above?

Thanks,

Presumably it prevents Grub from passing 'mem=xxxx' on the command line
when booting a Linux kernel. This was originally added because Grub was
briefly slightly better at working out the actual amount of memory in
the system.

Then for a long time Linux was much better, but Grub would still pass
its incorrect value on the command line, overriding the kernel's probe.

And now we just disable it and let Linux work it out for itself.

Grub 0.93 grub-2003-01-08-doc.patch DOC2000 trouble

I will try without the netboot code,
but it is not supposed to do anything unless
you drop to command and use {dhcp,bootp,ifconfig}
to config the network, then pull a kernel from tftp.

To clarify, it finds /boot/grub/menu.lst on first
partition of the DOC2000 (I assume the first to grub,
because if there is nothing on the DOC, it gives the
searching for menu.lst message on every possible drive
and partition combination), but will not boot the kernel
with "invalid partition table" (the board is at the lab
now), and the tab completion for "kernel (hd0,tab " fails
with the same error.

Anyway thank for the response and I will let you know
what happens without the netboot code.
