If you have no AT-style keyboard and only a USB model, you may need |

If you cannot find this option, it might be that it is always enabled |
|
|
and you can continue. It also might mean that the BIOS does not |
|
|
provide any emulation support (bad luck here). |

If you find the option and enable it, but the emulation stops working |
|
|
soon after the kernel started, then you have bad luck too. You could |
|
|
try the "bf2.4" flavor where the root floppy brings USB modules. If |
|
|
you are installing with floppy disks, you would need the keyboard once |
|
|
before the USB modules can be loaded. Specifying the "keytimer" option |
|
|
at boot prompt may help in this case. |

Sometimes, the emulation hangs but it wakes up after few minutes, so |
|
|
you could wait some time and try to continue. To fix this behavior, |
|
|
you could load Linux' own drivers for USB keyboards. For this, use |
|
|
"modconf" (Step "Configure Device Driver Modules") and load usb-uhci |
|
|
or usb-ohci modules. |
