In this tutorial I will use an A500+ rev. 8a motherboard with WorkBench 2.1 as reference.
I will try to make it mostly a bullet to bullet post, to keep it as short and clear as possible
Setting up your hardware.
First thing to do is to make sure your computer sees the extra memory that A314 will share with your Amiga, and make sure that the RTC gets detected. The amount of extra memory you will retrieve from the A314 depends on your motherboard revision, and jumper settings.
Below you can the most common A314 setups without any motherboard modifications made:
| A314 | Motherboard | JMP2 | JMP3 | JMPB3 / RAS0 | JMPB3 / RAS1 | Shared RAM |
|---|---|---|---|---|---|---|
| v1.1 | rev. 5 | set | open* | N/A | N/A | slow/ranger* |
| rev. 6a | set** | open | slow/ranger** | |||
| rev. 8a | open | set | chip | |||
| v1.2 | rev. 5 | set | N/A | open* | set* | slow/ranger* |
| rev. 6a | set** | open | set | slow/ranger** | ||
| rev. 8a | open | set | set | chip |
With these setups for rev. 5, and rev. 6a you will NOT be able to use the PiAudio, RemoterWB or the VideoPlayer - these features requires shared chip ram.
A note for those of you that happen to have rev. 3, set the A314 jumpers in the same way as for rev. 5. However, as far as I know there is no way to get chip instead of slow/ranger RAM.
