Is this about DOSBox?

The SB hardware is not touched as interrupt and DMA passthrough are a different level of complexity.

The secret is the harddisk interface. NT/W2k/XP have a fixed primary chipset-specific driver which must recognize the ATA device.

This multimeter looks a lot like the one with the rotary switch problem

Maybe there are driver switches to enable the legacy ports?

The rotary switch of the cheap ones will not last very long though.

Is this a PCI card? The base address might be at a different place then.

DOSBox does implement that part (it shows up in the I/O log also without video BIOS), but in vga_attr.cpp: Copy code to clipboard 1 /* Why disable colour planes? */

It took so long because I initially misinterpreted the 12 as decimal which would just make it change one color 😉

640x400 is the same ratio as 320x200, just more pixels

Here's the secret: iow 8 3c0 12, cs:ip c000:267e iow 8 3c0 7, cs:ip c000:267e The intensity bit is masked off in the attribute controller so all intensified colors are mapped back to the normal ones. DOSBox ignores this entirely.

Thanks, I got the alternate characters now. I'm only saying that real hardware doesn't work like ripsaws patch implements it. WP does not have "bold" characters on one of these graphics cards (the others not tested), so the problem is elsewhere.

I've tried 3 graphic cards and none of them drops the foreground intensity when character maps are changed. How do you get WP51 to display the extended characters? When I run 'wp charmap.tst' I get little blocks or normal characters instead of the alternate ones.

No editor that can do 'find in files'? 😉 It's in render_scalers.h and must be large enough that the mode can be displayed.

aaah SCALER_MAXHEIGHT.

Maybe try 0x4000 instead of 0x3000. It's the size of the screen in bytes aligned to 2^x. 80*66*2=2940h, 4000h being the closest.

Did you change your DRAM configuration jumpers according to the modules used?
