|
* Flags are zero or more of the following, ORed together: |
69 |
|
|
* |
70 |
|
|
* BUS_ISA_IDE0 Include wdc0. |
71 |
|
|
* BUS_ISA_IDE1 Include wdc1. |
72 |
|
|
* BUS_ISA_FDC Include a floppy controller. (Dummy.) |
73 |
|
|
* BUS_ISA_VGA Include old-style (non-PCI) VGA. (*1) |
74 |
|
|
* BUS_ISA_VGA_FORCE Include VGA even when running without X11. (*2) |
75 |
|
|
* BUS_ISA_PCKBC_FORCE_USE Always assume keyboard console, not serial. (*3) |
76 |
|
|
* BUS_ISA_PCKBC_NONPCSTYLE Don't set the pc-style flag for the keyboard. |
77 |
|
|
* BUS_ISA_NO_SECOND_PIC Only useful for 8086 XT (pre-AT) emulation. :-) |
78 |
dpavlin |
22 |
* BUS_ISA_LPTBASE_3BC Set lptbase to 0x3bc instead of 0x378. |
79 |
dpavlin |
20 |
* |
80 |
|
|
* (*1) For machines with a PCI bus, this flag should not be used. Instead, a |
81 |
|
|
* PCI VGA card should be added to the PCI bus. |
82 |
|
|
* |
83 |
|
|
* (*2) For machines where it is easy to select VGA vs serial console during |
84 |
|
|
* boot, this flag should not be used. Machines that "always" boot up |
85 |
|
|
* in VGA console mode should have it set. |
86 |
|
|
* |
87 |
|
|
* (*3) Similar to *2 above; machines that always boot up with VGA console |
88 |
|
|
* should have this flag set, so that the keyboard is always used. |
