and the keyboard don’t work, i have this problem also with the alpha 1, can i do something?

you can try safe-mode boot options and see if that will get Haiku to boot. Press [spacebar] while booting Haiku.

You would have to file a bug report. Search for similar issue first.

syslog is under /boot/common/var/log
