Multiple hardware devices can be initialized in parallel between vga initialization and option rom initialization. One can set this file to a value of zero to force hardware initialization to run serially. Alternatively, one can set this file to 2 to enable early hardware initialization that runs in parallel with vga, option rom initialization, and the boot menu. | sdcard* | One may create one or more files with an "sdcard" prefix (eg, "etc/sdcard0") with the physical memory address of an SDHCI controller (one memory address per file). This may be useful for SDHCI controllers that do not appear as PCI devices, but are mapped to a consistent memory address. +| usb-time-sigatt | The USB2 specification requires devices to signal that they are attached within 100ms of the USB port being powered on. Some USB devices are known to require more time. Prior to receiving an attachment signal there is no way to know if a USB port is empty or if it has a device attached. One may specify an amount of time here (in milliseconds, default 100) to wait for a USB device attachment signal. Increasing this value will also increase the overall machine bootup time. |
