/**
** USERCONFIG
**
** Kernel boot-time configuration manipulation tool for FreeBSD.
**
** Two modes of operation are supported : the default is the line-editor mode,
** the command "visual" invokes the fullscreen mode.
**
** The line-editor mode is the old favorite from FreeBSD 2.0/20.05 &c., the
** fullscreen mode requires syscons or a minimal-ansi serial console.
**/
/**
** USERCONFIG, visual mode.
**
** msmith@atrad.adelaide.edu.au
**
** Look for "EDIT THIS LIST" to add to the list of known devices
**
**
** There are a number of assumptions made in this code.
**
** - That the console supports a minimal set of ANSI escape sequences
** (See the screen manipulation section for a summary)
** and has at least 24 rows.
** - That values less than or equal to zero for any of the device
** parameters indicate that the driver does not use the parameter.
** - That the only tunable parameter for PCI devices are their flags.
** - That flags are _always_ editable.
**
** Devices marked as disabled are imported as such. PCI devices are
** listed under a seperate heading for informational purposes only.
** To date, there is no means for changing the behaviour of PCI drivers
** from UserConfig.
**
** Note that some EISA devices probably fall into this category as well,
** and in fact the actual bus supported by some drivers is less than clear.
** A longer-term goal might be to list drivers by instance rather than
** per bus-presence.
**
** For this tool to be useful, the list of devices below _MUST_ be updated
** when a new driver is brought into the kernel. It is not possible to
** extract this information from the drivers in the kernel.
**
** XXX - TODO:
**
** - Display _what_ a device conflicts with.
** - Implement page up/down (as what?)
** - Wizard mode (no restrictions)
** - Find out how to put syscons back into low-intensity mode so that the
** !b escape is useful on the console.
**
** - Only display headings with devices under them. (difficult)
