Got back home, it is exactly 632KB of conventional memory, so 8kb is missing, not 9kb. These are two screenshots, clean boot to DOS, the only thing running is SNARF, dos screen capture tsr that takes up 4K. I used it to take the pictures. MEM Filename SNARF000.jpg File size 27.08 KiB Views 394 …

Is that 631K total? Or 631k available? DOS itself needs memory to run, which includes IO.SYS and MSDOS.SYS, as well as the command interpreter. A plain install will not be loading DOS into the HMA, so it must be loaded low into the 640K area. Use MEM /C /P to see a breakdown of what is consuming …

Any chance the hard disk has some DDO (Dynamic Drive Overlay) installed? No DDO, just normal fdisk and format, using fat16. Also I should mention, no sound card, only video card and hard drive connected using pata cable on ide 0 of the onboard motherboard controller (also tried ide 1 connector). …

I have been testing an old motherboard from 1996, a Gigabyte Socket 7 GA586-ATS. Clean installed DOS 6.22 and when I run the mem command, conventional memory shows 631K instead of 640. This is with nothing loaded in config.sys or autoexec.bat, not even himem.sys, just a clean boot. The machine has …

Enabling UDMA in DOS with BIOS only assist has been hit and miss (mostly miss) for me depending on the motherboard. I use drivers from the following website to enable UDMA in DOS. I have had good luck using xhdd.sys & xhdd1.sys from the package. The drivers support a number IDE chipsets. http:// …

Can anyone get sound in Rambo 3 (Adlib option) using a ESS1868/9 card in Dos. Is this just one game that simply doesn't work with the card.

In Dos I did something similar a few years ago, using both card simultaneously. I would disable the poor/awful FM (OPL, ADlib etc) emulation of the sblive (port 388), and just keep it's digital sb16 emulation. Then, you don't need to disable ESS1868 and can use it for it's much more accurate OPL3 FM …

SBlive cards work with any V3 - V4 drivers but not V5. Audigy only with V5. SBLive cards can work with V5 using this approach . I haven't run any extensive tests to determine the differences in accuracy, other than noticing that there were no slowdowns with V5. That's a great guide . Your right …

I've noticed using SB Live cards FM will not keep a steady tempo depending on the 'intensity' of the song. This can be heard in Doom and Duke3D in both DOS and Windows, even causing some in-game stutter. It depends on the drivers that are used. A SBLive using its own native drivers has this problem …

Also the 100 MHz bus on 430FX doesn't sound right. The chipset doesn't support that. That would lead to 50 MHz PCI bus which wouldn't be healthy. Are you sure it is really bus speed and not CPU speed? Many Intel motherboards assume that when you insert a module into the slot you are extending the …

Only if you can change the chache speed and waitstates in bios somehow. If you pu a fastes chip somewhere it does not do anything, if you can not run it faster. It is this way with CPU-s, memory, and cache. There is options for memory 2-1-1-1 or 3-2-2-2. and only to disable the cahce or enable it. …
