| + | ===== SliTaz ISO image boot tricks ===== | ||
| + | |||
| + | The cdrom image has a hybrid format from version 5.0. | ||
| + | |||
| + | * It boots from a cdrom drive according to the el-torito specification as usual (BIOS or UEFI). | ||
| + | * It boots from a memory card / USB key using the syslinux hybrid format (BIOS) or using a FAT partition mapped in the ISO image (UEFI). | ||
| + | * It launches a USB boot key creation utility from Windows (32 bits). | ||
| + | * It can boot from DOS (real mode or virtual 8086 with EMM386) directly: | ||
| + | |||
| + | <code>C:\> ren slitaz.iso slitaz.exe | ||
| + | C:\> slitaz.exe</code> | ||
| + | <note tip> | ||
| + | The files bzImage, memtest and ipxe can boot with DOS too: | ||
| + | <code>C:\> ren bzimage bzimage.exe | ||
| + | C:\> bzimage.exe root=/dev/hda3 autologin</code><code>C:\> ren memtest memtest.exe | ||
| + | C:\> memtest.exe</code><code> | ||
| + | C:\> ren ipxe ipxe.exe | ||
| + | C:\> ipxe.exe http://myserver.org/boot.php</code></note> | ||
| + | |||
| + | * It is easily customizable with the iso2exe (compatible with taziso or tazpanel/boot/ISO mine) tool: | ||
| + | |||
| + | <code>iso2exe -a "lang=fr_FR kmap=fr-latin1 tz=Europe/Paris" -i myconfig.gz slitaz.iso | ||
| + | iso2exe -l slitaz.iso | ||
| + | iso2exe -r slitaz.iso custom.append custom.initrd | ||
| + | taziso slitaz.iso getcustomconf | ||
| + | taziso slitaz.iso isomd5</code> | ||
| + | <note tip>You can tune the boot process with your own /init script: | ||
| + | <code>#!/bin/sh | ||
| + | |||
| + | sed -i 's,^RUN_DAEMONS=",RUN_DAEMONS="dropbear ,' /etc/rcS.conf | ||
| + | cat >> /etc/init.d/local.sh <<EOM | ||
| + | /my/special/inits.sh | ||
| + | EOM | ||
| + | exec /init "$@" | ||
| + | </code> | ||
| + | Update the kernel command line: | ||
| + | <code>iso2exe -a "rdinit=/myinit lang=fr_FR kmap=fr-latin1 tz=Europe/Paris" -i myconfig slitaz.iso -f</code></note> | ||
