# Mostly copy-pasted from atari/Makefile.inc, including comments
# FIXME: It may be feasible to generate this file automatically
# NUMDRVS - number of supported drives (max. 16)
# 4 bytes for each device are statically allocated
# LINEBUF - support line buffered reads from E: (the number specifies
# the length of the buffer)
# UCASE_FILENAME - all filenames get uppercased
# DEFAULT_DEVICE - if the string passed to the uppercase function doesn't
# include a device (":" at position 2 or 3), provide "Dn:"
# as a default disk device
# n is the value of DEFAULT_DEVICE, unless DYNAMIC_DD is
# also set, in which case it's overridden by a runtime
# check (on SpartaDOS only)
# needs UCASE_FILENAME to be defined, otherwise no effect
# DYNAMIC_DD - determine default disk device at runtime (SpartaDOS only)
# needs DEFAULT_DEVICE to be defined, otherwise no effect

# The following defines are only used by the 'atarixl' target:
#
# CHARGEN_RELOC - If defined, CHBAS and CHBASE are updated when
# enabling or disabling the ROM.
# If the ROM is enabled, $E0 is written to CHBAS
# and CHBASE.
# If the ROM is disabled, the upper byte of
# __CHARGEN_START__ is written to CHBAS and CHBASE.
# USEWSYNC - If defined, the code waits for horizontal retrace
# before switching the ROM and updating CHBAS and
# CHBASE. This define only has effect if CHARGEN_RELOC
# is also defined.
# Disabled by default, you should enable it if the linker script relocates the
# character generator (like atarixl-largehimem.cfg).

# Disable if you don't want to use page 6 for mouse P/M data.
# If disabled, top of the RAM is used for P/M data.
