You'll probably be able to use mono as dual monitor on problematic boards and switch to it, but no hercules graphics mode will be possible. I was pretty sure based on address space that hercules graphics mode will always overlap with cga/ega/vga, except on very special cards that allow more options …

I have tried many ISA cards - including 8-bit ones with TTL output - with AGP boards: sometimes it works, sometimes doesn't. There's no general rule, eg. once I tried a Winbond HGC clone in an Athlon 1400 box, and it did work - but another card, based on the same Winbond chip, failed to work in that …

So it seems possible... Either recreate the fuctionality of CMSDRV/SBC-CMS drivers, or use V86 mode to capture direct I/O to CMS ports...

Not sure... OPL3 provides 5 percussion (noise) channels. SAA1099 provides 6 channels, CMS/GB has two chips = 12 channels... but can they all be used for noise?

The only reliable task killer for DOS is... the RESET button. In DOS, there's no memory protection, no hardware virtualisation. DOS programs - especially games - directly control all the resources. You may find some TSR to terminate the current process, but if a game takes over full control of the …

Maybe... but I wouldn't worry, 386SX-16 probably isn't fast enough to fully use 10 Mbps anyway... The CPU and RAM should handle 100Mbit even, but HDD in that age of machine is likely to tap out at 5Mbit, if not less. 100 Mbps = 12.5 MB/s 386SX-16 means 16-bit bus * 16 MHz = 32 MB/s In theory looks …

Yes, 3C509B is known to work in 8-bit slot, but: - must be set to IRQ that's present on 8-bit ISA, ie. IRQ 7 or lower - special packet driver may be necessary, but I'm not sure, it's possible it's only required for PC/XT Would it be slower than in 16-bit slot?

OK, I've found the installation guide for the original daughterboard, and indeed: Be careful not to insert your UltraSound too close to another card in your computer.
