# Configuration variables

# They can also be stored in a file /etc/lilo.defines, e.g.
# -DIGNORECASE -DONE_SHOT

# The variables configured in this Makefile are ignored if
# /etc/lilo.defines exists

#   ATARAID	  Enable 'ataraid' keyword and automatic marking of volumes
#		  as 'inaccessible'.  (testing only; DO NOT USE!!!)
#   AUTOAUTO	  Enable automatic generation of change rules for MS partitions;
#		  issue warning if "CHANGE AUTOMATIC" is assumed
# * BDATA	  Enable real mode gathering of system information for '-T'
#   BEEP	  Beep after displaying "LILO".
#   BOOT_FILE	  Append "BOOT_FILE=<path>" to the kernel command line.
#   COHERENT	  Make boot loaders (chain.b & mbr.b) compatible with Coherent
#		  by writing the boot device code to the memory copy of the PT
# * DSECS=n	  Set the number of Descriptor Sectors (n=1..12).  Each sector
#		  of the descriptor table holds 9..10 descriptors.
# * EVMS	  Enables support for booting from EVMS volumes. Requires a
#		  2.4 or 2.5 kernel patched to EVMS version 1.1.0 or later.
#   HP_TTRC	  Insert 150ms delay for HP TTRC card.  Affects 'second.S'
# * IGNORECASE    Image selection is case-insensitive. Passwords are still
#		  case-sensitive.
#   INITRDLOW	  Always load initial ramdisk images below address 15M,
#		  ignoring any 'large-memory' option in the config file.
# * LVM		  Enables support for booting from LVM partitions.  This will
#		  OOPS if you try to use this and are using a kernel < 2.4.7
#		  that has not been patched to at least LVM 0.9.1beta6.
#   NO1STDIAG	  Don't show diagnostic on read errors in the first stage
#		  boot. (not recommended)
#   NODRAIN	  Don't drain keyboard buffer after booting.
#   NOINSTDEF     Don't install a new boot sector if INSTALL is not specified.
#   NOSERIAL	  Don't assemble serial line support in the boot loader.
#   OLD_DIRSTR    Use old locations of config and boot files: (/etc/lilo)
# * ONE_SHOT      Disable the command-line and password timeout if any key is
#		  hit at the boot prompt.
# * PASS160	  Use 160-bit password hash (Secure Hash Standard, see
#		  FIPS PUB 180-1) instead of 64-bit CRC-32 hash
#   READONLY	  Don't write to disk while booting, e.g. don't overwrite the
#		  default command line in the map file after reading it.
# * REISERFS      Compile support for parts of LILO on ReiserFS.
#                 Requires header files for kernel 2.4.0test8 or later.
# * REWRITE_TABLE Enable rewriting the partition table at boot time.
# * SOLO_CHAIN	  Assemble all chain-loader functions into 'chain.b', 
#		  eliminating the need for 'os2_d.b'.
#   SUSPEND=	  Modify 'vmdefault' action if this partition type on C: drive
#		  is marked active; (Dell suspend partition is -DSUSPEND=0x84).
#   USE_TMPDIR	  Create temporary devices in $TMPDIR if set
# * VERSION	  Prints version string at LILO boot prompt.
# * VIRTUAL       Enable 'vmdefault', 'vmdisable', 'vmwarn' keywords; feature
#		  requested by VMware users (new, experimental)
#   XL_SECS=n	  Support for extra large (non-standard) floppies.
