|It seems, that I lost the mailing list registration. |So I renewed it ans I resend the mail (see below) ! It's ok, we got it the first time. Another thing you should check is whether the multiboot code enables the A20 line when you jump to addresses > 1M. If not, it won't work. The code that jumps to Linux (first32.c) starts below 1M, and enables A20 so it will work. Crash course in A20: This is a awful compatibility hack in ATs and above to do with the address line 20. Without enabling it, addresses above 1M will not appear properly. Actually every alternate M will be mapped wrong, IIRC. |
