Hey Guys… i did a much larger reply of my issue here - Zz9900 Guru RTG only - #18 by IvanEBC - but for now i have two simple questions,

Can the ZZ9000 be slowed down to Z2 speeds in my Amiga 4000 (Same as the X-Surf-100 has a jumper and that card also has issues running at Z3 speeds)
Is there a way to tell the card to NOT use the 256mb onboard memory, with maybe a program to run that reboots and “activates” the memory… till power down?

Thank you.

You can just use the Zorro 2 firmware. It will both slow down the card a bit and disable the memory. Also, the memory expansion in the Z3 mode is normally only active after the first reboot. Moreover, there is a Z3 “nofast” firmware version that does not have the extra RAM enabled.
