CSA Mega Midget Racer and HD mask question

[SimonV]

I am putting together my "utlimate A500", so far so good but I have some questions.

    - A500 rev6 with 1MB chipram hack and A501 512kb ram card or a KCS powerpc board
    - CSA mega midget racer with 8MB fastram and the maprom option
    - Alfa Data kickstartswitch 1.3 - 3.1
    - A590 with 1GB scsi drive and 2MB fastram
    - Dell external high density diskdrive
    - MV1200 external scandoubler / ff
    - Switch to swap Df0: with Df1: to boot from an external drive.

    The questions ... to get the ram working with fast file system, I should ad a mask in devs/mountlists according the CSA manual. How do I do that in OS3.1 ? see section 9 of the manual.
    http://amiga.resource.cx/manual/Mega-Midget_Racer.pdf

    I got it working by changing the MASK in with HDtoolbox but now I have DH1: NDOS ... fixed with Disksalv3 but I guess that's not the way to do it ?

    I also have this ramupgrade ( picture 3 ) that I maybe want to put in there if it is any good ? I can't find the model or manufacturer but the A500 kick 1.2 that I found it in showed 2Mb ram in workbench 1.3. So what am I going to see when I put it in my A500 ? I could test it but then I have to remove the CSA, I rather don't to that if not needed.

What does actually happen of what I am doing while changing mask ?

I maybe want to use PFS3 but if I do not mistake I have to change the mask for that also.

[SimonV]

read the manual section 9 ... you will understand.

CSA Mega Midget ram does not autoconfigure. It needs a line in the startup-sequence.

I do have a GVP harddrive somewhere, I think that does take 8Mb. The A590 max 2Mb I think.

[SimonV]

And can someone identify the ramupgrade?

[SimonV]

And I have to score a 2Mb chipram upgrade somewhere ...

[SimonV]

So I did find my GVP Impact A500 HD8+ so now it has 16Mb fastram. It seems to have the PC 286 IBM AT emulator in it.

I do not understand why he didnt make the aca500 for the cpu socket so it could be used for A2000 and CDTV also.

But as you say it is what it is and for the price it`s still nice hardware.

  About scoring an A2000 to find the chipramadapter .... that is exactly the way I found my Mega Midget Racer
