That works. I haven't old i386 PC, I have modern one, but Andrew's
suggest exited me and I tried to run the RedBoot on the modern PC.
Build the redbot image for pc target
mkdir ~/tmp/pc_rb
cd ~/tmp/pc_rb
ecosconfig new pc redboot
ecosconfig import $ECOS_REPOSITORY/hal/i386/pc/current/misc/redboot_GRUB.ecm
ecosconfig tree
make -s
ls -lR install/bin
install/bin/:
total 492
-rwxr-xr-x 1 sg sg 495854 May 7 14:03 redboot.elf
All rights. I did insert my USB pen. Ubuntu mounts this storage to
/media/disk, and I just did copy a future `kernel' there:
Install the image
cp install/bin/redboot.elf /media/disk
umount /media/disk
At the end, I appended these 3 lines to my GRUB's menu
title RedBoot (pc target)
root (hd1,0)
kernel /redboot.elf
Note: `hd0' is my SATA HDD and I used the `hd1' reference to boot from
my USB memory stick. You have to set up the hd's number correctly.
Usually, it's enough to look at `dmesg' output to resolve this issue.
I rebooted my PC and saw the expected choice in the GRUB's menu. I did
choose new menu's item... and saw that the RedBoot did start. It's pity
that I haven't old i386 PC. It looks like I won't got the RedBoot's
networking on my hardware. But GRUB runs the redboot image from USB pen
without any problems.
Thanks Andrew,
