Re: Keeping GDT, IDT and LDT tables within kernel memory?
Posted on 2018-04-20, 14:09
a ring3 program can load any selector from the GDT. its when it accesses memory through that selector that a fault will occur (eg: write to a cpl=0 page or something). you could just write a test and try it... if you even think about your statement for one second you would see your assumption is …

xmsdsk. call it from autoexec bat and not config sys, to bypass compatability mode and warnings and stuff.

most atmega is easier for isa card since they are 5v. does stm32 come in 5v version or only 3.3 + 1.8? I know a lot of PIC migrated down to 3.3 + 1.8 so its a pain to get 5v versions for stuff now. ugh
Re: How do I use MS-DOS DEBUG to patch EXE file?
Posted on 2018-04-13, 12:46
just remember to rename the exe to bin because debug cant save an exe once its loaded with relocations etc. and your offsets would be different, so rename .exe to .bin and your offsets stay the same and debug does not relocate the data.

loading unloading dos packet drivers is a sinch. I only load mine when I need it, so its the last TSR in the chain, then you can remove them no worries. I have a batch file called fget that will load my pack driver, dhcp an address, grab 1 file off my ftp, unload my packet driver. very handy. On my …
Re: Best dos extender?

dos extender games are best NOT run under windows. if SW is a watcom executable, you can try WDOSX or PMODE/W if DOS32a didnt work for you.
Re: Role of access rights in the segment descriptor cache?
Posted on 2018-03-22, 23:01
What I mean is, are they(those access byte's bits in the caches) used at all when already loaded into the caches, while accessing memory(e.g. instruction fetches(3 in UniPCemu), reading an offset(e.g. MOV CS:[0000], which performs a normal(1 in UniPCemu) read at CS cached descriptor offset 0&1)? Or …
Re: DOSBox vs ScummVM at this point
Posted on 2018-03-22, 22:34
ScummVM's Tandy sound used to be a complete and utter disaster "many years ago", sounding like a stadium organ reenacting the music in AGI. Nowadays, it's merely bad --- extremely aliased and with a ridiculous noise channel that sounds like a laser gun in AGI games (I just re-checked SQ2), wrong …

"I hope nobody ever sees my favorite game looking/sounding like this" (e.g. AGI). what AGI games exactly, dont look or sound like their originals? As the original author of the AGI engine in scummvm, things were pretty much exact between all the agi interpreter versions many many years ago when I …

present bit is used to denote if in memory or on disk in a paging file... conforming is for transfer in code segments, you cant transfer from a non-conforming to a conforming segment of the SAME privelege level, and you cant transfer to a high priv level (conforming or not). you'd need to check …

sure, but its backwards compatible. anything you need to know about the ct1350 firmware is in the sb16 firmware. dsp 1/2x commands list is known. extrapolate from there. its not hard to use your brain you know.

you could go one more step, convert gerber to schematic with altium. Missing one "small" step - firmware... SB all used an 8051 mcu, when you write DSP commands, they write directly to the 8051 dsp registers. sb16 firmware exsts.. a quick look with an 8051 decompiler tells you anything you need to …

take old creative CT1350 card. take hires photo front + back (so you can see resistor values etc). desolder all components. take another hires photo. convert photo to pcb gerber. done. you could go one more step, convert gerber to schematic with altium. charge exorbitant prices for your clone.
