I need some help with a macintosh peripheral I have. It's an OrangePC card, which allows you to emulate a PC within the mac operating system using actual hardware. My particular card has an AM386SX, a super math chips 80387, no sound aside from a beeper, and proprietary video (unless it uses the mac video). I believe the bios is ScatSX.
I am having an issue with the ram. Supposedly the processor can handle up to 16mb, but I dont think anyone has ever gotten past 8mb with these cards and have had them be stable. When I got my card, it came with 2 of the 4 ram slots populated. During boot it said 1mb, so you'd think that the 2 sticks are 512kb, right?
I took those two sticks out, found a matching set of 4, put two of those in and it also posted with 1mb. "Okay, cool. So if I put the other 2 matching sticks in, it should be 2mb, right?"
When I put the other 2 matching sticks in (4 total now) it posted with 3mb ram. Odd...I thought I had a dead ram slot, so I started shuffling the ram around. With 2 matching sticks in slot 1 and 2, it shows 1mb. With the same sticks of ram in slots 3 and 4, it says "ram count does not match CMOS--run SETUP" but never says how to get into setup (which I assume is the bios?). I also have other good known 1mb sticks of ram, all of which show the same error, so the ram isnt the issue.
There are a few articles on these cards discussing how to change the ram amount (one through the orangePC application, another through hitting ctrl-alt-esc), but nothing works . I cannot get the computer to produce a keyboard error either, which I heard will show the setup key sequence, and my application does not have the ram option (i think that was for a later pentium flavor card).
I've never messed with PC's this old (dos era stuff), so any help would be greatly appreciated. Ive tried on both 68kmla and mac rumors, but neither have been fruitful as these cards are hard to come by.
