| is set wrong.
| |
| | |
| If your board has 4 DIMM slots, you must use select this option, in

| | PCI_OPTION_ROM_RUN_REALMODE || devices || bool || Native mode ||
| |
| If you select this option, PCI option ROMs will be executed
| |
| natively on the CPU in real mode. No CPU emulation is involved,
| |
| so this is the fastest, but also the least secure option.
| |
| (only works on x86/x64 systems)

| |
| If you select this option, the x86emu CPU emulator will be used to
| |
| execute PCI option ROMs.
| |
| | |
| This option prevents option ROMs from doing dirty tricks with the
| |
| system (such as installing SMM modules or hypervisors), but it is
| |
| also significantly slower than the native option ROM initialization
| |
| method.
| |
| | |

| | YABEL_PCI_ACCESS_OTHER_DEVICES || devices || bool || Allow option ROMs to access other devices ||
| |
| Per default, YABEL only allows option ROMs to access the PCI device
| |
| that they are associated with. However, this causes trouble for some
| |
| onboard graphics chips whose option ROM needs to reconfigure the
| |
| north bridge.
| |
| | |
| ||
| |
| |- bgcolor="#eeeeee"
| |
| | YABEL_VIRTMEM_LOCATION || devices || hex || Location of YABEL's virtual memory ||

| normally located at 16MB.
| |
| | |
| ||
| |
| |- bgcolor="#eeeeee"
| |
| | YABEL_DIRECTHW || devices || bool || Direct hardware access ||
| |
| YABEL consists of two parts: It uses x86emu for the CPU emulation and
| |
| additionally provides a PC system emulation that filters bad device
| |
| and memory access (such as PCI config space access to other devices
| |
| than the initialized one).
| |
| | |
| When choosing this option, x86emu will pass through all hardware
| |
| accesses to memory and I/O devices to the underlying memory and I/O
| |
| addresses. While this option prevents option ROMs from doing dirty
| |
| tricks with the CPU (such as installing SMM modules or hypervisors),
| |
| they can still access all devices in the system.
| |
| Enable this option for a good compromise between security and speed.

| | USBDEBUG || console || bool || USB 2.0 EHCI debug dongle support ||
| |
| This option allows you to use a so-called USB EHCI Debug device
| |
| (such as the Ajays NET20DC, AMIDebug RX, or a system using the
| |
| Linux "EHCI Debug Device gadget" driver found in recent kernel)
| |
| to retrieve the coreboot debug messages (instead, or in addition
| |
| to, a serial port).
| |
| | |
| This feature is NOT supported on all chipsets in coreboot!
| |
| | |
| It also requires a USB2 controller which supports the EHCI
| |
| Debug Port capability.
| |
| | |
| See http://www.coreboot.org/EHCI_Debug_Port for an up-to-date list
| |
| of supported controllers.
| |

| If unsure, say N.

| |
| This option selects which physical USB port coreboot will try to

| use as EHCI Debug Port first (valid values are: 1-15).
| |
| | |
| If coreboot doesn't detect an EHCI Debug Port dongle on this port,
| |
| it will try all the other ports one after the other. This will take
| |
| a few seconds of time though, and thus slow down the booting process.
| |
| | |
| Hence, if you select the correct port here, you can speed up
| |
| your boot time. Which USB port number (1-15) refers to which
| |
| actual port on your mainboard (potentially also USB pin headers
| |
| on your mainboard) is highly board-specific, and you'll likely

| have to find out by trial-and-error.
