Hi mvs,
I haven't installed any anti-virus software till now, but I know from previous installations that the system's overall performance is impaired quite much when using anti-virus software.
I guess I'll kick out the Intel motherboard again since it's boot features are not what I expected.
Having all five HDDs connected the system tries to boot from an IDE HDD which is not a boot drive. Thereafter it stops instead of checking another HDD for a boot sector.
Regards
