I've tried this. It doesn't help. I don't know why, but symptoms are the same: after BIOS messages terminal (it is software one, of course) clears, cursor moves chaotically without any real output, and this behavior continues till I issue "Reset Terminal" command via terminal program menu. After terminal reset all output (from loader, kernel and, later, getty) shows normally. I've even dumped & disassembled new MBR code to be sure, that I installed new version. Yep, it doesn't contain this call in the beginning (after relocation). -- // Lev Serebryakov
