Quite many Acer net-/note-books models seem to be hit by this problem. I've got 3 acer netbooks with two of them shoving the problem. My Acer Aspire One 110 (quite old) does not have this problem. The following two Acer Aspire 1410 and Acer Aspire One 753 has the problem. I need to switch BIOS from SATA AHCI and back to plain IDE emu in order to make them boot FreeBSD. And the BOIS setting switch is not that easy because once the system hangs you cannot even get into the BIOS without removing the HDD. The system displays BIOS copyright message and then hangs forever (have waited an hour). This will go on until you remove the HDD then you can go into the BIOS and degrade from SATA AHCI to plain IDE emu - then everything will work and you can put the HDD back in. It is as if the BIOS expects something to be present on the disk. It could be the disk recovery partition - I think that Acer calls it something like D2D but even when disabling this option in the BIOS it still hangs with SATA AHCI enabled. At first I blamed the FBSD boot0 manager but I do not think that it is to blame anymore since the hang occours so early in the bios startup phase.
