BFG9060 Installation Guide
Installation of the BFG9060:
Hardware
Simply swap over your current CPU card (3630, Cyberstorm) and replace with the BFG9060.
Amiga Mainboard Jumpers
It is very important for the motherboard jumpers to be set correctly as per the tables below depending on what Amiga you have.
Amiga 4000D and A4000T
| J100 | J104 |
|---|---|
| 1-2 (INT) | 1-2 (INT) |
Amiga 3000D, A3000T and Replicas
| J100 | J102 | J103 | J104 |
|---|---|---|---|
| 1-2 (25 MHz) | 2-3 (INT) | 3-4 (ON) | 1-2 (INT) |
BFG9060 Jumpers
JP1 determines the clock frequency the card is working at. There are two jumpers, S0 and S1 (see image below), each consists of 3 pins 0, M, & 1.
Both jumpers can have 3 different jumper settings
- 0-M
- M-1
- Open (no jumper attached)
The following table shows how JP1 has to be set for the supported effective CPU frequencies.
Note that the the frequencies differ between 68060 and 68040 CPUs. The 68040 divides the set frequency by 2 internally, thus the effective frequency is always half that of the 68060 with the same setting of JP1.
| 68060 CPU | S0 | S1 | Notes |
|---|---|---|---|
| 25 MHz | 0-M | M-1 | Fast RAM will not be usable |
| 50 MHz | M-1 | M-1 | DEFAULT |
| 75 MHz | M-1 | Open | 68060 REV6 required |
| 100 MHz | M-1 | 0-M | 68060 REV6 required with heatsink and fan! |
Software:
To get the best performance, you will have to install the (mmu.library) available from https://aminet.net/package/util/libs/MMULib. And add the following line to the MMU-Configuration found in ENVARC:MMU-configuration:
SetCacheMode from 0x08000000 size 0x08000000 Valid CopyBack
Caching of Z3 is now enabled:
RAM-Cards, like BigRam or the Z3-Fastlane could not be cached and lost a lot of performance. You can enable caching for them via mmu.library now. If you have Z3-IO cards you want to disable caching.
MMU-library configuration would look like this:
Enable caching: For SetCacheMode {base} {size} Valid CopyBack
Disable caching: For SetCacheMode {base} {size} CacheInhibit NonSerial Imprecise
A working MMU configuration is available for download here
