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:

C:\> ren slitaz.iso slitaz.exe
C:\> slitaz.exe

C:\> ren bzimage bzimage.exe
C:\> bzimage.exe root=/dev/hda3 autologin

C:\> ren memtest memtest.exe
C:\> memtest.exe

C:\> ren ipxe ipxe.exe
C:\> ipxe.exe http://myserver.org/boot.php

• It is easily customizable with the iso2exe (compatible with taziso or tazpanel/boot/ISO mine) tool:

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

sed -i 's,^RUN_DAEMONS=",RUN_DAEMONS="dropbear ,' /etc/rcS.conf
cat >> /etc/init.d/local.sh <<EOM
