[syslinux] question about extlinux.conf on flashstick with ext2
Hi , I ve tested the pclinux minime on usb 1Gb and later 8Gb, with fat32 and syslinux boot , works splendid in Ram , and persistant saves on stick.. Now i want to try extlinux-boot with ext2 or 3 on the usb. With ext3 , i get constantly bumped to commandline, where i could type in the vmlinuz and initrd paths , but it cant make the loop-file of minime work..so it gets little panic :* But it wont read the extlinux.conf in /boot/extlinux on sda1 With ext2 somehow it reads and finds the extlinux.conf - but after vmlinuz and initrd - it bumps back to reboot... Done in short steps with other linux boot, where sdb1 is the usbflash: mkdir /mnt/sdb1/boot/extlinux xxx/extlinux361/extlinux# extlinux --install /mnt/sdb1/boot/extlinux umount /mnt/sdb1 xxx/extlinux361/mbr# cat mbr.bin > /dev/sdb mount /dev/sdb1 /mnt/sdb1 edit and save a /mnt/sdb1/boot/extlinux/extlinux.conf (last version) : default liveusb prompt 1 timeout 50 label liveusb kernel ../vmlinuz append livecd=../livecd initrd=../initrd.gz root=/dev/rd/3 vga=788 keyb=us bootfrom=/dev/sda1 changes=/dev/sda1/changes fromusb edit: *livecd= , *root= , *bootfrom= , **changes= , **fromusb comes from syslinux.cfg and *partly worked in ext3 different commandline-tryouts , but all ended shortly after the loopfile It feels like this extlinux.conf is kinda right way - but can i get further? with minime and ext2 /3 and the livecd.sqfs it uses ? /greetings - halfnewbie Gene --------------------------------- Sent from Yahoo!

When you say "wont read", can you explain what happens? Is the right partition set active?> With ext2 somehow it reads and finds the extlinux.conf - but after > vmlinuz and initrd - it bumps back to reboot...You get bumped to the command line because you have "prompt 1" in your config file, I presume you already realized that. Your command line is full of arguments which appear specific to your distribution (minime, I guess), including stuff like /dev/rd/3 which is old devfs syntax. I don't think what you're having here is a syslinux problem, as it appears to bootstrap everything.and I don't know if you'll find anyone on the list familiar with your specific distribution. You might want to ask in a minime forum. -hpa
