Move kickstart to fast RAM, MuTools alternative?
Hi!
I have an Amiga 2000 with an ACE2b installed for 2MB chip RAM, and a GVP Combo 030 Series II accelerator card with 16MB RAM. OS 3.2 and ROM. Were told I could gain some performance boost by using a utility called MuFastROM. Copied this over and edited my startup-sequence file according to the documentation, but were greeted with an error that an MMU is needed. Looking on the CPU, I see it is an EC variant, which omits this. Are there any alternative utilities that can move the ROM over to fast RAM, without requiring an MMU?

I'm not familiar with this board but a quick google returns this
https://amiga.resource.cx/exp/gforce2030 notes Kickstart remapping See if you can find the manual. |

Somehow I missed that detail... I'll have a look around for the documentation. Perhaps it is present on the disk images on the site.
Thank you for pointing it out! |

Questionable whether this works. The mmulib performs a function test of the MMU, and part of this test is to check whether remapping the ROM works. (Surprise, surprise!) Well, looks like it does not work in your case, so the CPU command would not work either.

The page linked by nogginthenog offers installation disks for download. They contain a GvpCpuCtrl utility which has a FastROM option. It works without a MMU.

I personally upgraded by Combo to a full 030 relatively cheaply, but for other reasons. If it is *only* necessary to remap the ROM, then GvpCPUCtrl does that for you. There is then, however, no write-protection for the ROM if that should matter.

If he has an EC030 than what he really has is the G-Force 030 variant. The older Combo 030 had the full 68030 SMD soldered on the Board. This unit does not support the hardware MapROM function. |

Thank you everyone for your replies. I managed to sort this out on my own after getting that initial lead.
Found a user manual here. However, I found everything I needed on one of the floppy disk images in a readme file there. As Thomas Richter pointed out, all that is needed is GvpCpuCtrl from the disk. Copied it into C and added it to my startup-sequence file with the string "C:GvpCpuCtrl FASTROM >NIL:" and it worked! Workbench is a little bit more snappy now. Attatched some pictures with a before and after using the bustest command to compare speeds. This card isn't a permanent solution, as it will eventually be replaced with a more modern card. If I intended to keep it, I'd consider dropping in a full CPU. The readme file on the disk even states no modification is needed, if changing the CPU is desired. Learned a few new things now. Another small step for a novice Amiga-user. |
