MC68040 or MC68060 Based Accelerator For the Amiga 2000

1. It should be noted that there are four programs needed by the 68040 processor to insure maximum performance These are CPU SETPATCH 68040 LIBRARY and KSREMAP The latest of all four programs are included on the Install disk and these can be automatically installed if selected by the user Only one of these programs KSREMAP is supplied by TekMagic the rest are standard Amiga programs The programs include with the Installed disk are noted below KSREMAP This program will copy an image of the Kickstart ROM to Fast RAM on the accelerator board for Increased performance of the entire system It can be installed and loaded automatically every time the system boots as noted above or it can be used by selecting its icon or as a CLI command Arguments REMOVE Reset the system ROM vector to point to the Amiga s ROM chips and frees any fast memory previously reserved for remapping the ROM FASTPREP and EXPERTPREP 2 5 These are the same programs provided with later SCSI controllers from Great Valley Products GVP and are used to format and Prep hard disk drives These programs have been licensed for use with this accelerator Please refer to the accompanying manual for Instructions on using these programs Note that the only change is that the program works with the new SCSI device driver TEKSCSI2 DEVICE found in the autoboot ROMs on the A2000 accelerator board The program icons reflect this change but if eith2. 32 megabyte 8MBx32 or x36 Note 16MB SIMMS or higher requires that Jumper JR4 be set for 16MB mode With any amount of memory less then 16MB R5 should be set for 4MB mode 9 When installing SIMMS of different memory capacities you must install the SIMMS of higher capacity first In other words the largest SIMM should be installed into the lower numbered banks For example if you had a 16MB SIMM and a 4MB SIMM the 16MB SIMM would be installed in socket CN 1 and the 4MB SIMM in socket CN2 Also it should be noted that when mixing SIMM Jumper JR5 should be set to match the largest SIMM size In our example above this would require JR5 to be set for 16MB SIMMS Because of the way that double sided industry standard SIMMS are designed it is accessed as two separate SIMMS This adds another twist if you install a double sided 72 pin SIMM two of the GVP 64 pin sockets are disqualified Consequently if you install two double sided SIMMS you cannot install any GVP SIMMS This caveat does not restrict the 72 pin SIMMS in any way however The 68040 68060 processor s Burst mode is also supported in specific configurations e You must have an even number of SIMMS installed e in pairs The SIMM pairs must be of the same capacity i e a pair of 4MB 8MB etc SIMMS All memory mounted on an A2000 040 060 board is configured as Extended RAM This provides for maximum system expansion while maintaining complete compatibility with other
3. 68060 PROCESSOR UPGRADES You will be happy to know that your A2000 accelerator was design to work with the Motorola 68060 50MHz processor and can be upgraded by your dealer By upgrading your accelerator to a 68060 you can expect a significant performance increase To upgrade your accelerator three changes must be made to the board First the socketed 68040 must be replaced with a 68060 processor Secondly the system clock 33MHz or 40MHz should be replaced with a 50MHz system clock Finally the boot ROM must be upgraded to support the 68060 The 68060 processor requires several modifications to the Kick Start ROM for compatibility and performance enhancements and it is the job of the boot ROM to patch the operating system to support the 68060 properly Please refer to your dealer for availability of the 68060 upgrade kit

RAM however is reached as four banks corresponding to up to four occupied SIMM sockets Connectors CN1 and CN5 are treated as the first single bank CN2 and CN6 comprise the second bank CN3 and CN7 correspond as do CNA and CN8 comprise the final bank For each bank if a SIMM is installed in one of that bank s sockets then the other socket cannot be used For example if you install a AMB 72 pin SIMM into socket CN1 you cannot insert a GVP SIMM into Socket CN5 You could however insert a GVP SIMM into socket CN6 and consequently you would be prevented from inserting a 72 pin SIMM into CN2 This may sound confusing but it can be easier to understand if you remember the following two provisions 1 You can t install more than four SIMMS total and 2 Remember the four banks and that using a SIMM in one socket of a bank prevents the use of the other socket Bank 1 CN1 and CN5 Bank 2 CN2 and CN6 Bank 3 CN3 and CN7 Bank 4 CN4 and CN8 Now that you think that you understand this concept it gets more complicated This is because there are a multitude of 72 pin SIMMS that can be used Be thankful that there are only two types of GVP SIMMS 4MB and 16MB Here are the various types of industry standard 72 pin SIMMS that can he used single or double sided SIMMS this adds more possibilities 1 megabyte but why bother 2 megabyte 256kx32 or x36 4 megabyte 1MBx32 or x36 8 megabyte 2MBx32 or x36 16 megabyte 4MBx32 or x36

12. existing Autoconfig memory peripherals 32 Bit Memory Whatever amount of memory is installed in your system and no matter how it is configured the A2000 040 060 board will always attempt to use 32 bit Fast RAM before any other kind Only after its store of 32 bit memory has been consumed will the system use 16 bit memory In this way the accelerator board makes most efficient use of its resources for the maximum attainable performance Users should be aware however of the possibility that some applications may not work with Extended RAM on the A2000 accelerator board These applications will generally not work on an Amiga A3000 or A4000 either Such programs are not 32 bit pure their authors made some assumptions about the addressing range of the target computer and used the high order address bits in unauthorized ways The most surprising 32 bit impure program is AmigaBASIC Some programs while they cannot access or use memory beyond the Autoconfig range will operate happily by ignoring Extended memory Such programs will work on a 68040 equipped system Still other programs cannot cope with Extended RAM but may not run correctly on the 68040 processor The solution for such software requires rebooting your system under 68000 control Refer to chapter 5 Software Installation for details on the use of support software As Workbench 2i 3 x and the current crop of programmers tools become more widespread we expect to find fe
