ACA1233n MapROM and Elbox Mediator

I've been having a slight problem with my ACA1233n MapROM working with Elbox Mediator 1200TX Black series.

My setup is as follows:

Amiga 1200 Rev 2B board

ACA1233n 40Mhz version with RTC addon

Voodoo3 16Mb video card

Adaptec SCSI 2940UW connected to a SCSI hard drive and CD-ROM

Creative SoundBlaster 1238 CT4750

Realtek RTL8139 10/100 network card

I have ACAMapROM /I q as the first line in my startup-sequence but when Wwhen running ACAInfo from shell once Workbench is loaded it always shows the MapROM status as disabled.

If I boot with no startup-sequence and run the maprom program manually, it works properly, on the soft reboot it shows the MapROM status as enabled. It's only when booting to Workbench it shows as disabled.

I'm wondering if, because the Mediator uses the RAM on the video card for DMA access, is it mapping the video RAM to the memory area where the MapROM utility expects to find the ROM loaded?

Hi Jens, thanks for the prompt reply. Looking at the results of the bustest it appears to be working properly. Here are the results:

Right - so not a "showstopper", it's working, but not properly displayed. I'll put it on the list of things to be checked, but please understand that in these busy times, this cannot have high priority.

HI ,

no problem, it's just a cosmetic issue,as long as it is actually working then I have no problems. I understand you are very busy with other projects and this hardly warrants immediate attention. I am very happy with this card so far and it was just a niggling little thing anyway.
