yes I tested everything and looked at the values with ac97test. Nothing, no sound at all 2400/76 is and stays at "ffff" either 2400/76 is the wrong value 2800 is the correct number, so sbemu-nambar.exe I changed the "SB-EMU" in my start.bat with all three versions linked hier (nambar, nabmar, debug …

what about sbemu-nambar.exe then? still no sound? Last option is dumping all codec registers in pre XP windows (allows access to hardware registers without drivers so ac97test should work) where sound works and comparing to what sbemu is programming in, maybe its something stupid like volume being …

How does Rise of the Dragon or Heart of China run on EGA? Both have minimal requirements of 8088 with 640KB of ram. We are in a thread named "Is there any reason to install more than 1 MB RAM on a 286 PC?" Are there any non Windows VGA games requiring more than 1MB that will run acceptably on 286? …

286 was EGA territory, nothing requiring VGA and more than 1MB would be playable with one exception being Windows. I think I played many games on my 286 back then that supported VGA, so for me that was always the beginning of the VGA-era. But the 286 covered a pretty long time span requiring VGA …

I don't see the point of dumping every single 4.13 model card - we already have enough information to definitively determine that the effective code is identical. Who cares about what fill bytes are used or whatever? cmon, dont spoil the fun all the sound blaster collectors are having right now! :)

Well, it depends. It can be MMIO or I/O ports (depends on the least significant bit in the BAR address of the PCI config space). Practically, MPXPlay/sbemu don't check that and always assume I/O ports . Also, the I/O enable bit in the PCI Command Register must be set for the PCI device to react to …
