Porteus 2.0 and Grub4DOS [SOLVED]

Post#1 by Ed_P » 06 Feb 2013, 22:57

Hi.

I'm running Grub4DOS 0.4.5c 2012-06-19 and I use it on my USB Flash drive to boot several ISOs including Porteus 1.2. I'm trying to add the Porteus-v2.0-rc2-i486.iso to the drive and am encountering an error when it boots. It stops when it can't find porteus-v2.0-i486.sgn.

These are the two menu items that I'm using:

Code: Select all

title Linux\n 257MB\n Porteus-v1.2-i486.iso
map --heads=0 --sectors-per-track=0 /ISOs/Porteus-v1.2-i486.iso (0xff) 
map --hook
root (0xff)
kernel /boot/vmlinuz from_iso=/ISOs/Porteus-v1.2-i486.iso autoexec=startx
initrd /boot/initrd.xz

title Linux test\n 242MB\n Porteus-v2.0-rc2-i486.iso
map --heads=0 --sectors-per-track=0 /ISOs/Porteus-v2.0-rc2-i486.iso (0xff) 
map --hook
root (0xff)
kernel /boot/syslinux/vmlinuz from_iso=/ISOs/Porteus-v2.0-rc2-i486.iso
initrd /boot/syslinux/initrd.xz
I removed the cheatcode as suggested in another thread but when I tried the "find" command mentioned in the other thread it returned an invalid command response.

Code: Select all

grub> find /ISOs/Porteus-v2.0-rc2-i486.iso -type f

Error 27: Unrecognized command
ls /ISOs/ however does show the v2.0 iso amongst the others.

Do I need a different version of Grub4DOS or a different cheatcode?

tia

Please also try following the advice given by fanthom in the following thread. Pay attention to extracting vmlinuz and initrd.xz from Porteus ISO.

Thanks brokenman. That was the other thread that I was referring to.

I've never had to extract vmlinuz and initrd.xz from any other ISO to which I have about 10 and that doesn't appear to be the source of this problem. But it's an interesting approach.

Solved!! :Yahoo!:

This works.

Code: Select all

title Linux test\n 242MB\n Porteus-v2.0-rc2-i486.iso
map --heads=0 --sectors-per-track=0 /ISOs/Porteus-v2.0-rc2-i486.iso (0xff) 
map --hook
root (0xff)
kernel /boot/syslinux/vmlinuz from=/ISOs/Porteus-v2.0-rc2-i486.iso autoexec=startx 
initrd /boot/syslinux/initrd.xz
The v1.2 "from_iso=" cheatcode has been replaced with a new one named just "from=".



Someone needs to update this http://porteus.org/component/content/ar ... tcode.html webpage for v2.0's change.
