:P
1 - noapic is a cheat code reported as below:

"noapic noagp noapm nodma nomce nofirewire nopcmcia noscsi noswap nousb nosmp noaudio
Skip parts of Hardware-detection, In case of a failing hardware autodetection, try booting with any of the "no-" options as shown in the table above, like in knoppix noagp noapm noapic nodma nopcmcia noscsi nousb to skip some critical parts of the autodetection system. The "noswap" option is useful for a forensic analysis without touching existing swap partitions."

Is it equivalent to "apic=off"?

2 - How long does testmem take? It seems to me this test did not work properly as I escaped from the test after almost 1 hour (pass #4 was going on at that time) and I could not believe it was OK though no error was reported.
Any idea?
