Re: What do you use your ramdisk/ramdrive for?

Does COMMAND.COM ever get called after boot that might get an improved speed being referenced from the ramdisk? Yes, it often happens that COMMAND.COM gets reloaded, eg. Norton Commander reloads it whenever running a program. Copying COMMAND.COM to the RAMdrive, and doing eg.: SET COMSPEC=D:\ …

I'm only wondering why the RESET pins in the middle of the board... It would be logical to place them in the corner, and it seems that either JP11 or JP13 must be RESET...
Re: CARDINAL -286 Build

JP12 seems to be Turbo Switch. JP15 - Speaker. JP14 - Power LED and Keylock. JP11 and JP13 - Reset Switch and Turbo LED, probe them with a LED first, while toggling the Turbo Switch. In general, don't probe with switches, as they do total short. A diode, however, should be safe - no total short.

Wait... You have both SERIAL PORT 1 and SERIAL PORT 2 configured as COM1 (3F8h)... change JP6 to COM2 (2F8h) - Pins 1 & 3, 2 & 4 closed.

DOS software for post-ISA sound devices

Vast majority of DOS software only supports ISA sound cards... however, there's a few programs with native support for newer hardware: PCI, PCIe, USB, and onboard chips acting as PCI devices... Live! Module Player Mpxplay QuickView Pro - with external drivers Anything else?

Re: Covox and win98se
Posted on 2024-05-08, 08:40
So does this mean that for the same sound quality, covox is much less load on cpu than pc speaker? No. Can't achieve the same quality. Covox is a normal DAC, and - properly built - can be as good as any 8-bit sound card. But I've never heard PC Speaker playing PCM at comparable quality. Perhaps in …

I just had a look at some code for PCM playback via PC Speaker and Covox... There shouldn't be significant difference in CPU load between those two devices: - timer interrupt frequency is the same - for Covox, the interrupt routine simply outputs a Byte to the LPT port - for PC Speaker, the …
Re: DOS 7.1 PCI NIC packet driver issues (no packets received)
Posted on 2024-05-07, 10:26
Well, it seems I'm underestimating DOS... Just did this experiment: set some IRQs to "Legacy ISA", to force three PCI devices to share one IRQ: - LAN - CNET Pro200, based on some Davicom chip - sound - SB PCI 128 - USB And it still works fine, both the packet driver with mTCP, and the NDIS2 driver …
Re: DOS 7.1 PCI NIC packet driver issues (no packets received)
Posted on 2024-05-07, 08:57
Isn't the IRQ used by the NIC shared with some other device? It would be logical to cause problems in DOS, but not in Windows: Windows drivers may properly support IRQ sharing, but DOS drivers - not necessarily.
Re: Covox and win98se
Posted on 2024-05-07, 08:47
Last time I tried it - probably 30 years ago - it only allowed to play short PCM samples in RAM, and didn't allow to do anything else while playback. Same as the PC Speaker WAVE driver. So, before you make a Covox, you can try the PC Speaker drivers (I think there's more then one), and see what's …

Do you have all voltages needed for that card on your ISA bus? Not sure what version you have of that card, TP or Coax? Ethernet cards only need +5 V. Yes, Coax transceivers need 9 V, but even this is provided from the +5 line, using a DC-DC converter. Overall, if an SB-compatible sound card works, …
