�a c'est safest, mais plus lent

...je lis:
"idex=ata66" : informs the interface that it has an 80c cable
for chipsets that are ATA-66 capable, but the
ability to bit test for detection is currently
unknown.
ok, Linux ne d�tecte pas le type de c�ble donc tu l'informes. Mais �a ne
change pas la fr�quence du bus pci (cf 2�me r�ponse � Nicolas Rueff, �
