you have several options.
1) if you have GRUB or another boot loader. you can simply copy from the iso image in the folder / boot files bzImage, vmlinuz-2.6.30.6-slitaz (the kernel) and rootfs.gz (image filesystems). for the GRUB menu.lst file written
#=========
title SliTaz boot (Kernel 2.6.22.9)
kernel (hd0, 0) / slitaz / boot / bzImage root = / dev / null vga = 792
initrd (hd0, 0) / slitaz / boot / rootfs.gz
#=========
2) create a Live USB using a utility tazusb

booting from USB slitaz.3.0.iso mount in / media / cdrom
# Mount-o loop-t iso9660 slitaz.3.0.iso / media / cdrom
and can run the installation script

# mount -o loop -t iso9660 slitaz.3.0.iso /media/cdrom

done ! installed on harddrive !
Chrome is working, flash also !
Now what about my pcmcia dwl-650+ wireless card ?
Googling and I found an interesting site :
http://acx100.sourceforge.net
But it's a little bit complicated
chipset : acx100

thanks for any help !

I have the same chipset on a zycell pci wireless adapter.
The easy solution that fully supports WPA security is to install slitaz-2.0.iso
Use tazndiswrapper which is included to install the winxp drivers
I found ndiswrapper is broken on slitaz-3.0 , the adapters radio receives the access point's broadcast but no dhcp assigned or network connectivity with a fixed ip address.
If you want to try ndiswrapper on slitaz-3.0 you have to install it:
perl-core, ndiswrapper-driver, tazndis tazpkgs in that order
http://doc.slitaz.org/en:guides:wifi-easy
The acx100 open source driver would have to be compiled and doesn't provide WPA security.

will try solution 2 before reinstalling slitaz-2 ...
I tried pclinuxos which was fine but kde4 mess'd up plasma
lost my desktop and I had enough... so lets try slitaz I should say

I just installed slitaz 2.0...
there's no google chrome package :(
ahhhh :( I have no sound !!!
