If you just want to display the licenses that have been installed for your card, use this command: There may be special characters in the code - just make sure that you get all five characters of the code right, otherwise we cannot sell you any license!įor any licensing to be changed, the jumper must be put into position "unprotect". The warranty ID is case-sensitive, that means a capital letter is different from a lower-case letter. By starting ACAcontrol without any arguments: The warranty ID of the card will be shown as "Serial". On the retail box: The white sticker on the right side of the box shows the same code. You can find it in three places: On the card itself the silver sticker shows the 5-character warranty code. To purchase licenses, you need to know the warranty ID of your card. It is contained in the above LHA archive. LHA archive containing ACA1221 library, ACAControl, ACAgov and ACAclock Licensing operationsĪll licensing is controlled with the ACAcontrol commandline tool. The ACA1221 is a purely asyncronous card, and will run at the exact given frequencies, even if the host computer is an NTSC version, which is usually clocked at 28.63636 MHz. Please note that although the highest frequency may look like the card is clocked syncronously to the A1200 mainboard (because it's the same as the chipset base frequency), the two clocks are not syncronized at all. The four different CPU clock rates are generated by dividing this clock by the following values: This clock always drives the SD-RAM controller of the card. The ACA1221 uses a base clock of 85.12548MHz. Please use the ACAclock tool to set the speed, or the ACAgov CPU governor to automatically set the CPU speed according to CPU speed requirements If you have purchased an overclocking license, you can set 21.28 or even 28.38MHz clock speeds. This has been implemented in order to give harddrives enough time to spin up and be available after a cold-start, even under Kickstart 3.0. After Autoconfig operations have been completed, the CPU clock will be increased to 17.03MHz, and caches will be enabled. The ACA1221 starts up at it's slowest speed of 9.46MHz. This is not an issue, as it will not keep the system from starting at all it's just a property of the card with certain A1200 motherboard revisions, and it's perfectly normal behaviour. This may happen on a cold-start or after a reset. The ACA1221 may start up with a red screen in some cases. The second "female" clock port uses memory address 0x00d90001. If you already have a RapidRoad inside your A1200, we recommend to use this dedicated port instead, as it is considerably faster than the "normal" clock port: You will get over 1MByte/s performance from USB mass storage devices, if the highest overclocking rate of the ACA1221 is enabled. For passing power to RapidRoad, the white power output of the ACA1221 can be used. A polarity "nose" helps avoiding connection mistakes. A clock port cable is not required the card must be pluged directly to the ACA1221 as shown in the picture. The female clock port has been designed for the RapidRoad USB host controller. This means it can be used in addition to any clock port device and/or RTC that occupies the other clock ports. The second clock port of the ACA1221 is independent of the internal clock port of the male clock port. Note that if you want to use the internal and the ACA1221 male clock port at the same time, you may only use one RTC module and one clock port expansion card, but you can never use two RTC modules or two clock port expansions at the same time. This male clock port is extremely useful if you own an early A1200 mainboard that has the clock port assembled in the wrong position. In that case, the internal clock port of the A1200 may not be used for such an expansion, but can be used for an RTC module. That means you can also use it to connect a Catweasel MK2, Silversurfer or Delfina card. As opposed to earlier accelerators with an RTC port, this port is a straight copy of the internal clock port of the A1200. The first clock port is mainly meant for an RTC module. The ACA1221 features two clock ports for adding hardware expansions.
