All the Zorro based kickflashers need to reset if they contain a rom image or OS 3.5/3.9 updates. The only difference is that it happens a lot earlier in the boot process (ie. happens before disks are found and dos is started).
Does the Amiga boot up a lot quicker now ?
Does it reboot after there is hard drive activity?
Also, there`s updated Kickflash software and firmware on Coyote Flux`s site..just cos a card is new doesn`t mean it has them,cos you never know how long the dealer had it in stock before he sold it.
