boot-problem using grub
hi everybody
i've got a problem with my ts-5700. i tried to set up my own linux-image on a cf-card and set up grub. if i boot this image in a vmware, grub loads the kernel and the boot-process beginns (it failes at "kernel panic: vfs not syncing.." but thats not the problem..) on my ts-5700 grub starts as usual with Code:
Loading stage 1.5. Code:
[01;C4H [01;C8H [01;C8H [01;C8H [01;C8H [01;C8H [01;C8H [01;C8H [01;C8H [01;C8H any ideas? thanks, toby |
no ideas but some further questions
how do you know that your computer will allow boot device .flash memory card? how do you know that you successfully installed grub into that card? 2) I am a dinosaur but I am not aware of grub recognising cf cards in the device list. can you post in the links that indicate your knowledge? |

Thanks, but...

any other ideas? i think it's an issue of displaying the boot-menu, but that does not explain, why it is not booting the default entry then.. |

yes well I was trying to explain that I do not have a cf card, so can not test what I am about to say.
you may need to use another computer, if you have one to try this 1) format your card to a bootable kernel format eg ext2 mkfs.ext2 /dev/sdx where sdx is what your card is detected as 2) populate grub onto it mount /dev/sdx /mnt/temp cd /mnt/temp mkdir grub cp /usr/share/grub/i386-pc/stage* /usr/share/grub/i386-pc/e2fs_stage1_5 /boot/grub/menu.lst /mnt/temp/grub ...(or where ever grub backup lib is,eg it may be /lib/grub/) 3) edit the grub menu either open a editor and navigate to /mnt/tmp/grub/menu.lst or vi /mnt/tmp/grub/menu.lst 4) concerning your menu concerns, I do not have a single board low power computer so I am guessing that you can still have boot order of cf card.....you may know the answer but your answer did not help one bit and I do not blame you for dismissing my ignorance. assuming your card can be the first boot device try hd0 in the menu. 5) populate the balance of the operating system that you prefer.Since you mention linux-image but give no details I assume you know more than me on that matter. good luck |
well, thats right what i did so far.
i built up my linux from scratch on that cf. the problem still is, that grub is not providing any output on the sbc but these [01;C8H-strings and not booting any further on the sbc but does on a machine that can provide vga-output.. |
have you tried a boot parameter?
eg vga=normal vga=ask vga=791 append it to the kernel line eg kernel /boot/vmlinuz root=/dev/sda1 ro vga=ask edit is is quick link on vga codes go as basic and as ugly as you can if vga=ask does not ask edit 2 found the best link http://wiki.antlinux.com/pmwiki.php?n=HowTos.VgaModes |
sick of edit, to that link, you make vga=integer so not vga=0x301 but vga=301
|
thanks, but i don't think
a vga-option will work on a console..? |
try a line like this I found
console=ttyS0 TERM=vt102 from here http://tldp.org/HOWTO/PA-RISC-Linux-...earlyboot.html do a search of console to find the section console http://www.win.tue.nl/~aeb/linux/lk/lk-2.html 2) if none of them work, including trying vga, yes i know, then try the noboot options like noapci noagp nodhcp noapic nodma nofirewire nosmp noraid |
