I should have had pci pnp, but not ISA or BIOS pnp |

did I? well I meant to have that out, but it doesn't matter - I set up ACPI :) |

yeah because this is what boots your kernel if you used genkernel |

this is only the default resolution for VESA frame buffer, and won't affect |
| 21 |
the booting of your kernel, but makes it look nice - u can set it higher like |
| 22 |
1024 for your system if you like |

once again, just perrty things :) |

| 28 |
yes, so that you can easily use udev if you want to (just emerge udev) |
| 29 |
devfs will still be mounted if you dont' have udev. |

dunno - depends on your chipset, but from your other email I guess silicon |

true, that is a min-atx, so you only get 3pci.. still 2 ide devices on one ide |
| 55 |
chain will always be dog slow. |
