Title: Installation Problems on Dual socket board
Post by: arflinux on October 28, 2004, 11:33:21 AM: I have a Dual socket motherboard with 2 x 1GHz P3 processors 1.5G ram (ASUS CUV4X-D) Motherboard
SME 6.0.1 installs with out a error message and reboots the problems start after it rebbots i select SMEserver SMP and just halts at various stages on boot up mostly at the 2 CPU.

I thought it was the processors so i tryed installing FEDORA CORE 2 this installed ok and up and running.
tryed WinXP Professional up and running installed Service Pack 2 not a problem.

any idea what could be the cause off my problems

Thanks in advance
Andrew

but the question that i now ask is what does append="noapic" actually do

VIA chipset? Plenty of ideas. First and foremost, dump that board and get a Serverworks based board.

Title: fix for apic errors on smp boxes
Post by: BolO on September 07, 2005, 03:13:51 PM: Very simple to fix this issue, after installation upon getting to grub screen hold down <ctrl-x> and the press <tab> to see kernel options, type for example SMEServer-smp and after that add the string noapic and press enter... Remember once the machine is booted to permanently fix this by adding append="noapic" to your /etc/lilo.conf file...

Post by: henry44 on September 07, 2005, 07:16:17 PM: As I understand, apic is related to power management (turning off the computer at power down, etc.) and some chipset/bios implementations of apic aren't compatible with some Linux implementations, hence the boot errors.

I think it might be smarter to have the default state be apic=0 rather than apic=1.

Post by: BolO on September 08, 2005, 09:16:35 AM: I think that you are thinking of ACPI (Advanced Configuration and Power Interface) where as APIC is Advanced Programmable Interrupt Controller and causes kernel panic errors on alot of smp boards. So like I said, that will fix it!

For MS Windows, only 2000, XP, 2003 and higher support it, and it must be enabled in the bios when the OS is installed. It cant be swiched on afterwards.

It has to be disabled in the bios for 95, 98, and ME, or you get crashes.

Many motherboards coming out now dont have the option to disable it anymore, which might be a problem.

Be best to use it if possible. I'd guess SME 7 would support it, but havent tried.
