Hi, I tried to prepare a bootable Pharo ISO image based on Tiny Core Linux. Namely on MicroCore (kernel 3.0.3) that was extended with WiFi support. There is standard Pharo 1.3 image with OSProcess and CommandShell installed on the Smalltalk side. The resultant image has about 37 MB. Download: http://www.windmap.cz/playground/pharo/pharo.iso If you want to add it directly to your Grub menu, you may do it without need of extra partition. To the grub.conf add something like: title Pharo root (hd0,1) kernel /boot/pharo/vmlinuz vga=791 quiet initrd /boot/pharo/tinycore.gz where vmlinuz and tinycore.gz are the only files needed from the ISO image. Remastering: unpack: zcat tinycore.gz | sudo cpio -i -H newc -d pack: find | cpio -o -H newc | gzip -2 > ../tinycore.gz better compression: advdef -z4 tinycore.gz create ISO (you need unpacked original ISO image): /bin/cp -pfr tinycore.gz boot mkdir -p newiso /bin/cp -pfr boot newiso mkisofs -l -J -R -V TC-custom -no-emul-boot -boot-load-size 4 \ -boot-info-table -b boot/isolinux/isolinux.bin \ -c boot/isolinux/boot.cat -o pharo.iso newiso Cheers, -- Pavel
