Hi, after long debugging of the suspicious Warning: unable to open an initial console that turned out to be actually fatal for d-i installer (because it starts with busybox init </dev/console >/dev/console and so missing /dev/console kills it) I have just found out that simple
console=tty0 in bootargs (kernel parameters) fixes it and the d-i boots further on my AfterBurner040. Easy, isn't it? The question for kernel hackers is why on AfterBurner this 'console=tty0' is required while on other machines it's not needed. The d-i doesn't work yet, it stops somewhere at switching console to UTF, but for me it's a huge success :-) Petr
