Does this machine have a RAID controller or any kind of funky disk controller that it is booting from? The disassembly looks like: 00000000 0F20DD mov ebp,cr3 00000003 81E500F0 and bp,0xf000 00000007 0F20C2 mov edx,cr0 0000000A 0F01E0 smsw ax 0000000D A801 test al,0x1 IOW, the BIOS on this thing is doing bad things by trying to enter protected mode on its own. With paging even. *sigh* I wish BIOS writers would grow up and use the defined BIOS calls for accessing upper memory and what not instead of getting cute and doing it all themselves. It prevents the BIOS from working in VM86 mode like we do in our boot process. This really needs to be fixed by the BIOS writers if possible. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
