Although they're better than the ones Windows installs upon detecting the card, they sound rather wonky in DOS mode and appear uncertified in DirectX. Did not the AWEs have had some sort of DirectX support ? Perhaps their drivers are more advanced and can be used with the SB16, too. (Speaking under …

Hi, I remember that Win95 and Win98 had a slightly different caching mechanism. Windows 98(SE) was even able to execute programs directly from virtual memory (if they were aligned to 4KiB boundaries). Have a look at the link in Windows 95 OSR 2.5 and 128-256mb ram

Hello, is that the card ? http://www.vogonswiki.com/index.php/ATI#R100 The issue sounds like an IRQ conflict (pun intended). Apparently, the ATI 7500 reserves an IRQ for its own. The BIOS settings for PnP/Legacy have no effect for PCI (or AGP) cards. http://www.overclockers.com/forums/showthread.php …

Hi Alex, I am not very used to the Monkey Island series, but I vaguely remember to have heard something about speed sensitivity of the AdLib detection.

OK, then my understanding was partially correct. its like using external MIDI device but internally connecting it to the SB. Yes, you are right. The MPU-401 is essentially like a serial port, but for MIDI. At least in the common, non-intelligent UART mode. DB50XG and and the other wavetable cards …

Actually, it is the reverse. The DB50XG was the very first Yamaha XG MIDI device. :) Generally speaking, a MIDI daughter card or WaveBlaster card connects to the WaveBlaster header on sound cards. This header is wired to the sound card`s MPU-401. Just like the MIDI cable that connects to the game …

Um, not sure. But you can make your own using an Trident TVGA9000i chip. That is an low-end design, however. But it might be still good enough to do the usual CGA/HGC/EGA/VGA/SVGA modes. Except Composite CGA, of course. ISA Super VGA card http://www.malinov.com/Home/sergeys-projects/isa-supervga

As far as I remember, old SCI0 games had an issue with some other synths (CM-64, etc) because the engine/driver was erroneously playing other, non-MT32 tracks (AdLib ?) via MIDI. Anyway, since you get a buffer warning, it likely is something else. I would try to lower the DOSBox cycles to something …

Good morning, Before you installed that EGA card, did you disable the on-board AGA graphics somehow ?

Maybe the DMA controller is having trouble. The Floppy Disk Controller uses DMA2/IRQ6. Also make sure things like EMM386 or UMBPCI are not running while you are testing. so how would i go about check for those? Hi, CheckIt! checks the DMA channels if you select the mainboard test. IRQ6, on the …

You'll probably find the 10GB HDD still wont work. 486's usually recognise 500MB or 8GB drives. My experience was similar so far. They usually support CHS and E-CHS (aka Large).
