So, apparently a lot changed with this program from 1996 to 1998. what did not change is that all those cards Hoontech, Terratec, Guillemot use SAM9 4 07 and not SAM9 7 07 chip. So, basically, what I am saying is that there is not a single known case of 94DINIT working with SAM9707, which …

Paging @dreamblaster to clone this.. no need to clone anything, here is the CD: https://www.vogons.org/viewtopic.php?p=1135020#p1135020 with the schematic and the GERBER files. So, if you're that interested you can order PCB for yourself right away. it's another story if you can source any of the …

@Ozzuneoj: at least "Hoontech SoundTrack 97 ISA" DOS initialization is done in 2 steps: 94DINIT F=HOON4D S=GMSBK040 P=330 MXSET97 DEFAULT.MIX where "HOON4D" in your case is "97PNP2" (the BIN file from your CD, i.e. Dream Firmware file for that specific design) and "GMSBK040" is "GMBK9708" So, I …

@Ozzuneoj : unfortunately, when in that old thread we actually cracked the encryption of all Roland GS ROMs SC-55, SCC-1, up to SC-88, etc. there was no any interest in helping me extracting the same sound from the 94B banks and compare them or even we make 94B bank with the sounds from SC-55 ROM …

Wow, on the CD in "SNDBANK\LETCUST.PDF" is actually recognized by their CEO back then, that they copied the Roland GS sounds without permission, what I pointed out few years ago here: https://www.vogons.org/viewtopic.php?p=920784#p920784 basically, as far as we know "GSSBK320.94B" bank is close to …

maybe, I don't understand the question, because PCem/86Box is using VHD for HDD image format - that is directly mountable as Windows drive: "Windows Computer Management --> Storage --> Disk Management --> Action --> Attach VHD" I wonder how you created PCem/86Box hdd image in the first place, …

@MMaximus : thanks, your physical Model80 machine has the exact same BIOS version as 86box VM Model80. So, I think DMQS gets disabled most likely due to what @SSTV2 noticed about the overlapping ROM ranges. I hope with help of 86box developers all those findings be put together and soon we have …

https://www.ardent-tool.com/video/XGA2.html XGA-2 all of them have slightly different versions but as far as IBM is concerned, is equivalent in specs, officially. There is no such as 45MHz ramdac, this is rated around 75MHz for all of these. thanks, it's all getting together, because in IBM 's "XGA …

I don't have access to my machine at the moment but I bought my XGA adapter from WBST on amibay a few years ago. Here is the archived thread - you might be able to get more info about the adapter from the picture same as @SSTV2, i.e. "RAMDAC with Heatsink". according to @SSTV2 those are the 1st …

it's the first revision with a heatsinked RAMDAC I don't know which one is the 1st revision and so here I count on your good knowledge about PS/2, but then it means even the 1st XGA-2 is 90MHz RAMDAC, i.e. "Index 53H=0x53", I guess that means there are no "Index 53H=0x50" (45MHz RAMDAC) XGA-2 cards …

@MMaximus and @SSTV2 : just out curiosity how the DAC chip looks on your cards from the above 3 options - maybe we can at least in the end of 2022, almost 2023 tell, how at least some of 90MHz DACs are looking, as you both have cards with 90MHz DAC for sure.

@MMaximus : currently, most helpful would be "xga2 -s >> xga_full.log" from your Model 80 to investigate the DMQS support issue. Other tests would be mostly redundant, but it depends on what XGA-2 card revision you have - if you look here: https://github.com/86Box/86Box/issues/2983#issuecomment- …

good catch and observation - probably another bug, I did not even noticed that, because instead "PS/2 SCSI Adapter" as in your case, I have "ESDI Fixed Disk" in my config and thus no conflict is shown explicitly (to draw my attention on it) like in your case, where C6000 - C7FFF is obviously subset …

@ MMaximus : please, when have time, do collect: Copy code to clipboard 1 xga2 -s >> xga_full.log because you have Model 80 - same as what 86box emulates and yet in your system DMQS works, while it fails in 86box. thanks.

XGA2 Index 52H value: 21FA; XGA2 Index 53H value: 2153. Great! Now thanks to your tests, the undocumented Index 53H became really obvious: * on XGA-1 card its value is 0x30 and DMQS reports: 3 - XGA implementation function level identifier 0 - XGA implementation resolution level identifier * on XGA …

@SSTV2 : wait, on 2nd thought, I think the result is so weird in the machine with XGA-2 card, because there is bug in my XGARD52H/XGARD53H - in machine like yours with 2 x XGA cards, one XGA-1 (on-board) and one XGA-2 as add-on card, my tools always pickup the XGA-1 card and in that case the on- …
