Re: Running Windows 98 on newer hardware w/o hypervisor

Hello. I am wondering if someone who has had a job in the industries of computer science and engineering could help me get my ideas in order. Is there a cost effective way I could have developed by paid experts a means of running Windows 98 using SeaBios on a hardware target that is both supported …

Re: Intel publishes a white paper on x86S, a 64-bit only architecture

I see x86-S as an attempt which in theory would reduce CPU die size and make it more efficient by removing legacy stuff that aren't used in modern software development (x87 FPU, port-mapped I/O, 16-bit addressing mode, etc). But the "die size" of this is completely insignificant -- it was already …

VirtualBox actually is trying to bring back binary translation (to run under Apple Silicon). But yes, this is a pretty big deathblow to 16-bit virtualization (and native running...). And likely 32-bit OSes too. I don't understand why Intel would do this -- the power/performance improvement is likely …

Running 98 SE on a intel 13700x , I saw the same error messages as in the missing TLB invalidation screenshot, both virtualization as well as booting it natively, so I guess we can add the intel 13th gen to the list of affected CPUs. If someone has done experiments with similarly newer Intel CPUs ( …

Do EtherDFS drives report the correct free space on the server and LFN (assuming a TSR is loaded fro LFNs) or is it short names with a max 2GB? TIA! No and no. The network redirector interface only has 16 bits for reporting the disk size, in terms of cluster size, so 32 K * 65 K ~ 2GB. Most DOS …

You can also get a small x86 tablet and use regular Windows and regular Dosbox on it. E.g. older "Atom"-based Surface Gos are likely available for 200-300$ now and they have more than enough horsepower for Dosbox (not for 86Box, though). I used to run my own fork of Dosbox on Nokia Maemo phones …

Personally, this worries me a bit. The statement is a bit hollow, I think. The specs of the test system are not just vague, but unknown, even. . I think that one of the main pros of (2D/GDI) hardware acceleration would be in emulation, where e.g. the native Windows rendering code would be run under …

These "temporary file names" remind me of some CD copy protection schemes, e.g. SafeDisc/SecuROM. I wouldn't have paid much attention to it, but since you mention the problem is related to an IDE controller setting...

SB16 has always been in a purgatory state of working/not working. The main wave part works but the midi part doesn't. VMWARE SB16 doesn't work either. I mean it works but not the MIDI part of it. Since 2015ish VMware has a bit of initial support for SB16 FM (OPL3) & MIDI. It is hidden behind a .vmx …

DOS never did this %..% variable substitution in the interactive command line. It was only available in batch files, and the FOR command. This is unlike NT's and 4DOS, I believe.

You can trivially do 4K Windows 9x (and more) under VirtualBox with the open driver @ https://www.os2museum.com/wp/windows-9x-video-minidriver-hd/ Just edit the .inf file before installation to add the resolutions you'd like, as the author recommends on the blog post.

sound is the prime complaint when trying to run a DOS-based Windows (SB16 is broken) It's not that bad, give poor ol' little VirtualBox a bit credit :) Many games and OSes do work out of the box, that thread is a bit too aggressive :) I'll buy that for DOS gaming it's probably hit or miss, and …

I don't think you want a redirector, rather you really want a device driver so that DOS can mount your USB disk and handle filesystems for you. It'll be simpler than a redirector, even! Note that a device driver .sys file can be loaded at runtime using any of the popular DEVLOAD equivalents. It is …
