Mediator and PCMCIA

DDNI · 25 July 2008, 20:46

I am having some trouble with graphical disruption on my system.
Re size, hide and close gadgets are becoming corrupt.

The corruption only occurs when I use a PCMCIA wireless card.

My A1200 has a Mediator PCI 1200.
I am using afa_os v4.2 on OS3.9 bb1+2
My Gfx card is a Voodoo3 graphics card with the latest drivers and MMCD updates. My screen resolution is 1024x768
I bought the Mediator second hand. It came with the MMCD and it has had the Mach chips upgraded.
My Mediator memory window is set to 8mb.

I have found a temporary fix to the corruption, by setting the Mediator memory window to 4mb, the corruption does not occur.
This however means any graphic intensive applications, run out of Voodoo memory if the WB screen resolution is above 640x480. (800x600 doesnt work either)

I have been told that this PCMCIA problem only occurred with Mediator boards that had the old mach chips.
Is there a fix to my problem?

Many thanks...

ps. are there any differences between the Mediator PCI 1200 (with upgraded mach chips) and the Mediator LT4?

The two solutions I can think:
1- Upgrade the MACH chips (expensive);
2- Take the PCMCIA nic out and install a PCI card with the prism chipset on the Mediator.

Just the MACH chips.

I think I have the latest Mach chips....? Came with MMCD??

I have to have wireless, the Amiga is nowhere near the hub... is there a wireless prism2 based PCI card that works with the mediator?

Latest MACHs are now with MMCD 1.30 which we will have next week.

What accelerator are you using?

Hi, I am using the BPPC in my signature.

Guys I have been doing some reading around.
It would seem that the A1200 Mediators use the same gfx address for their 8mb memory window as the 4mb memory window reserved for PCMCIA. Indeed the MedConfig utility only allows the Mediator memory window to be set to 4mb if PCMCIA is to be used...

Have any Elbox Mediator revisions/software/Mach chip upgrades addressed and fixed this issue?

Interestingly the graphical trashing doesnt seem to occur if I force apps to use the workbench screen. If they open their own custon screen then holy hell breaks loose... Is this because workbench confines the Mediator to the first 4mb of gfx space whereas custom screens go into the shared memory area?

Am gonna give this a bump....

Has any one else encountered this PCMCIA issue? It has been discussed in the yahoo groups mediator list, without a reasonable solution...

Didn't see the thread on the ML, but I can give a suggestion: did you try cardpatch (the executable used to solve lock-downs on Workbench when a PCMCIA NIC is hooked)?

DDNI · 28 July 2008, 21:37

@rkauer, thanks for the help. I am using cardpatch and cardreset in my User startup sequence. The problem sadly persists...

I guess its a limitation of the Classic amiga 680EC20 only having 10mb (?12mb) of address space...
