|
|
Hi -
I have recently aquired an Intel Entry Server which I would like to install Gentoo on.
INT4541 3.2GHz p4 CPU LGA775 (with em64t)
SE7221BA1-E Motherboard
2 x SATA 300GB hard drives
2GB DDR2 533 RAM
Every time I try and boot from the amd64 live CD I get the following error:
"Your CPU does not support long mode. Use a 32bit Distribution"
I have tried with the minimal 2006 amd64 livecd and the universal 2006 livecd, both with the same above error.
I know this processor and MB support 64bit operations... So what could be the problem? There seems to be very little googleable info on this problem.
The only thing I can think of is that the MB bios does not include em64t support. The MB itself is specified as supporting em64t, so should there be some option in the bios settings that would indicate em64t is enabled or not?
Also. if I install gentoo as usual in 32 bit, can I then just emerge a 64 bit kernel and build the system with the correct settings in /etc/make.conf. Or would it be best to boot, say, ubuntu amd64 live and then install gentoo from a chrooted shell whilst already running in 64 bit?
Thanks in advance |

Have you looked at your bios? Make sure you don't have some strange setting set that is interfering. Also verify those CPUs are EM64T processors, it should say somewhere in your BIOS the details of your CPUs. _________________ I am not anti-systemd; I am pro-choice.
