# Packages of interest:

# nvidia-trimslice

# For booting off a USB stick on a TrimSlice with an SSD, you'll have to change the root
# to sdb1 and ext2load to use usb 1:1 (not tested), since by default, U-Boot
# initializes device 0, which is the SSD. If you don't have an SSD, the above
# USB-bootcmd-file.txt is what you want for booting off USB.

# The mem and vmalloc variables correspond to how much RAM you're allocating the graphics
# chip, which does not have its own memory.
