I tested SliTaz 5.0 RC1 from CD on the following three computers Quanmax KUBE-8060 (a fanless box with HM55 chipset and i5 M 540 CPU), Quanmax KUBE-8080 (a fanless box with QM67 chipset and i5-2430M CPU, just bought) and on a Samsung 5 Series Ultra 530U3B notebook.
All three do very well with SliTaz 4.0, but I had some problems on all three with SliTaz 5.0 RC1. The audio and the alsamixer work only when logged in as root. The ethernet is working out of the box on all three. But on the KUBE-8080 which has a LAN1 and LAN2 I had to disable LAN2 in the bios to use LAN1 as with SliTaz 4.0. When LAN1 and LAN2 are enabled, the connection to the internet is on LAN2. The video is good on the newer Quanmax KUBE-8080 at its monitor's native resolution 1920x1200 and also on the Samsung 530U3B at its native 1366x768, but not on the Quanmax KUBE-8060 at 1920x1200, showing only 1024x768 pixels in the upper left corner of the 1920x1200 monitor, the rest is dark.
Saving an image from the midori browser, closes the browser. The galculator works only after reinstalling, but the tazwikiss not even works after reinstalling.
I use SliTaz 4.0 on KUBE-8060 and KUBE-8080 with GRUB4DOS using a MENU.LST
title SliTaz 4.0 GNU/Linux 1920x1200x24
root (hd0,0)
kernel /bzImage lang=en_US kmap=us screen=1920x1200x24 rw autologin
initrd /rootfs4.gz /rootfs3.gz /rootfs2.gz /rootfs1.gz
Now I regret, that there is no screen option anymore with SliTaz 5.0 RC1. Also the Monitor Settings menu gives the native resolution as the only option. So I can't use resolutions like 1280x800 anymore with SliTaz 5.0 RC1 on my 1920x1200 monitor.
Sometimes I boot an iso image of SliTaz 4.0 using GRUB4DOS with the MENU.LST
title SliTaz 4.0 ISO CD image
map --mem /slitaz-4.0.iso (hd32)
map --hook
chainloader (hd32)
This method doesn't work with slitaz-5.0-rc1.iso
I hope, that SliTaz 5.0 becomes as good as SliTaz 4.0.
