Since DOS6 cannot see more than 32MB, these games ran without error. I cannot remember the game(s) but I do know they needed XMS and not EMS. I don't think the limit is 32MB. Even XMS 2.0 implemented in HIMEM.SYS of DOS 6.22 supports 64MB of memory. It's because the 16bit DX register that stores …

"Conservative Swapfile Usage" is your friend here. If you can, make sure to give Win98 asa close to 512MB of RAM as possible and the line above should limit the amount of swapping done by Windows9x's memory management.

Because it's not more compatible, and the hassle of dealing with a multi-boot environment (at least when something breaks, as is the case here) is larger than the hassle of bringing the utilities over once. Actually, I can think of several popover TSRs DOS 7.x breaks (in addition TSRs written with …

Any chance you could force the AWE64 to be on the port220 IRQ7 and DMA1 ? Also, what if you chose soundblaster for music (adlib) AND sound effects? Does this make a difference? I too have an AMD K6-III at 400MHz and never had an issue, but I use an AWE32. Seeing as how the AWE32 and AWE64 are so …

Hello all, I have recently taken my old awe 64 gold out of the cupboard and started tinkering with it. All was running fine for about 1 hour, then the audio volume level dropped dramatically.

You can only switch from real mode to protected mode, but not vice-versa. To get back to real mode, you must reset the CPU (note: the CPU, not the system, which can be done in software with tricks). It's only the 286 that needed to be reset. 386+ are perfectly capable of exiting protected mode. But …

In general, Config.sys boot options is one of these things where I found that people mess way too much with them. It seems that people get into the mindset that if a feature exists, then it must be good for something and so should be used gratuitously. I used to do this myself, and then I found out …

Completely pointless, as %config% contains the name of the selected menu item automatically.

How would you handle different configs such as: - Conventional memory - XMS - EMM386 …

I had a similar situation where I needed more control over options from my config.sys file. Like, say you also use the boot menu to run things like softMPU which only works if EMM386 is loaded, or conversely MXK6OPT which can only run if it isn't. You can use SET xxx=yyy as early as config.sys in …
