Instruct Ubuntu to boot to RAM from flash drive using unetbootin
I hit tab and replaced quiet splash with toram. Do not use TORAM=yes, just use toram. This worked for both Ubuntu and Mint, although some versions of Mint needed toram -- toram. Hope this helps as I am doing some modifications along these lines.
Example of my modded syslinux.cfg:
initrd=/ubninit file=/cdrom/preseed/linuxmint.seed boot=casper toram --
You may add whatever other flags between toram and --, but
keep in mind some may crash your system.
To add a boot parameter press F6 or to type it manually Down then Up
