Ok, so I''m playing with an IT8212 dual channel IDE controller in an old Dell PowerEdge 1300. I managed to compile the drivers and install them as a module with mkinitrd and everything worked fine. I''ve now got my hands on a second PIII-450 to make this a dual-cpu box and with the kind help of others here installed the smp kernel - this kernel will boot but doesn''t like the IT8212 drivers. The precompiled drivers (for an older 2.4 kernel) from ITE do include a SMP version so I presume there are specific settings for a dual-CPU box but what I''m trying to figure out is how to compile an SMP version of the drivers - all that you get for driver source code is a .c file, a .h and a Makefile - would it just be switches to make the SMP version or do I need to be booted to the SMP kernel to compile the driver? In any event, I''d be happy to reinstall from scratch or just boot SMP without the RAID controller working at this time but how do you ''deactivate'' the drivers installked with the mkinitrd command!? Thanks. NK

I normally do my own drive setup, but figured I''d just throw 4.0 on this box to find any issues. It made it through some of the init scripts... I don''t remember exactly where, but I think it crashed when looking for a kernel, which would have been about Grub time.

Thanks - since the box isn''t that critical I''ve just fed in the Centos-3 disks again, scrubbed the boot disk and reinstalled the OS - as there were two processors in situ it has installed the SMP kernel. Once this was done I just did a ''make'' on the IT8212 drivers source code and then modprobe/insmodded it and it''s working fine - the two 160GB disks are resyncing now. I understand from some forum posts I found elsewhere that IT8212 drivers will be/are native to the latest 2.6 kernels so maybe things will be easier in the future. -----Original Message----- From: centos-bounces@caosity.org [mailto:centos-bounces@caosity.org] On Behalf Of John Hinton Sent: 08 March 2005 15:29 To: CentOS discussion and information list Subject: Re: [Centos] Fun with RAID (Again!)
