here we go - custom DS2000 firmware, based on FW 00.01.01.00.02 (imho latest)
tricked into believing its a 350Mhz model, thus enabling 200M BW limit & 1ns timebase.
i also tried 500Mhz, while this allows 500ps TB, it does not make a difference on screen (probably hitting some hardware limit)
the only thing i dont like is that the model type should be changed too as it still says DS2202.
i also tried options de-install/install - worked fine.
to the best of my knowledge the change does not affect the bootloader, its only a modification of the application payload, so i consider
it safe to play with - there is always the possibility to flash back a standard version. i killed it several times during testing, no problem whatsoever (just flash back another version)
nevertheless - no guarantees whatsoever if u want to try this ! - no whining if something breaks !CHG3_RILOL.GEL - >
http://www.sendspace.com/file/ybkx21download, rename to "DS2000Update.GEL" -> put on USB stick -> install via bootldr method (power on + HELP)
