I planning make a high end win98se ( later dos and win games) and Xp for Dos box and early XP on same machine. Because someone was able to make Win98SE on Z170 chipset working - highend could be misleading:) But i know what you mean, i865 is fine, dos compatibility mainly depends on sound cards and …

Just for example how Vmware Workstation 12.5.9 is fast in DOS mode, i used DR-DOS results would be probably same with MS-DOS. Physical CPU is Core i7 4770S quad, results - 70 second - when i use Auto Virtualization engine, when i forced Virtualize Intel VT-x and Virtualize CPU performance counters i …

Yes. you use at least SB !Live, SB Audigy - Windows for which exist Win98 drivers, there are lots of models, Aureal V1/V2 and Yamaha 7x4. My recommendation is Aureal or Yamahas. For info is in this …

Koltoroc: Thanks for explanation, i will still keep my hope that some new good device with $100 price tag will emerge.. These Startech VGA2HDMIPro are something like that, but they are seems to be for now available for such price only in USA and shipping and taxes make it unreasonable. It would …

No, just the NTLDR files are necessary (NTLDR, NTDETECT.COM, BOOTFONT.BIN, BOOT.INI) Thanks, only other problem could be partition boot record, because sure if for Grub2 is enough just copy the files to partion, its looking for partition boot record... But with Dos / Windows 9x you will need …

I added some DR-DOS TaskMgr info to first post, its all theoretical, read all its docs, you will come hammer time.. On paper its sound very good, but we will see real compatibility with games. My testing could be influenced but Vmware DOS bugs, but unless someone will figure out how to start DR-DOS …

there is this saying, the truth hurts. He is right, you know. When someone need to use such sentences like do it yourself and other far fetch arguments, he is usually not right.

Quake 1 is protected mode software, it shouldn't need EMS at all. Disable the EMS page frame unless its actually needed by older software. Most people use EMM386 exclusively to take advantage of its creation of UMBs for loading drivers high. Its a bit more complicated, i need EMS, because other DR- …

So probably last big problem which we have to solve with DR-DOS is EMS settings, but default there is EMS size 3MB and there is not parameter how big it should be in emm386 helpdevice parameters.. And Quake 1 is crashing on it, not enough EMS. I found that there is some EMMXMA.SYS which could be set …
