# ROOT_DEV specifies the default root-device when making the image.
# This can be either FLOPPY, CURRENT, /dev/xxxx or empty, in which case
# the default of FLOPPY is used by 'build'.

ROOT_DEV := CURRENT

# If you want to preset the SVGA mode, uncomment the next line and
# set SVGA_MODE to whatever number you want.
# Set it to -DSVGA_MODE=NORMAL_VGA if you just want the EGA/VGA mode.
# The number is the same as you would ordinarily press at bootup.

SVGA_MODE := -DSVGA_MODE=NORMAL_VGA

# If you want the RAM disk device, define this to be the size in blocks.

RAMDISK := -DRAMDISK=512
