# RSSCOUNT should be set to the number of REs in your boardset.
# Octane SE and SI, Indigo2 SolidIMPACT and HighIMPACT should be 1
# Octane SSE, SSI, MXE and MXI, Indigo2 MaxIMPACT should be 2

# If you are unsure of the RE count of your boardset, execute the
# command 'gfxinfo' and look for a line such as:
#         Product ID 0x0, 2 GEs, 2 REs, 1 TRAM
#                               ^^^^^^^

# When set to 2, the resulting mode file should be stored in
# /usr/gfx/ucode/MGRAS/vof/2RSS/, otherwise the mode should go in
# the usual /usr/gfx/ucode/MGRAS/vof/ directory

# DB32 should be set to '1' to enable large double-buffered visuals

# INTERLACED should be set to '1' for interlaced modes, '0' otherwise

# STEREO_FMT should be set to '1' to make a stereo mode, '0' otherwise

# VERT_SERRATION should be set to '1' if your interlaced mode requires
# a serrated vertical sync pulse. (?)
