It doesn't have the right parts on it

EEPROM is the small 8pin chip next to the big AWE chip.

Voltage regulators aren't populated so there is no direct support for 3V CPUs anyway. The regulators could be restored and basic 3V CPU support can then be achieved.
Re: PCI Riser Card capacitors - required on all thin clients?

There's R4 that should connect -12V from edge to the slot on the riser, put a solder bridge or 0ohm resistor on it and there should be low current -12V functionality on the output once more. 100mA is enough for the COM port level translator chip and shouldn't be a problem for the few opamps or …

Thinclient may have a PSU that only puts out +12V, +5V and +3.3V but not the -12V which is only ever used by COM ports and some sound cards. One inductor leg going to ground and diode cathode going to the other leg strongly suggests the SMPS is wired to inverting configuration, in a positive …

All better cards use -12V present on PCI for the analog section and lack of it will result in probably very distorted sound or no sound at all.

I actually think negative voltage generation, the inductor and diode orientation seems to suggest that.

You move R18 to R17 and R19 to R16 to get 2MB support. There's no difference between 0 ohm resistor and a solder bridge or bodge wire, except current andling capability where the resistor will not reach wire or bridge ever 🤣.

The missing parts are for a voltage regulator, though what voltage it generates I'm not sure of.

Faster RAM isn't gonna do anything at all there. What you can do is solder a 2MB RAM chip there instead of the 512KB one. There's couple 0 ohm resistors to move to allow it to work.

Go to program properties and untick the warning message and perhaps tick "prevent ms-dos progams from detecting windows", a PIF file is saved that windows will use next time.

on older BIOSes the strings are in plaintext though not always in the same place. Some sort of heuristics based search would be viable as the strings follow fairly predictable format.

I have one Creative branded 16MB Banshee and a Voodoo2 with 12MB of DRAMs that have 110MHz written on them, no clue who made the card though. Both have been modified to have heatsinks and fans, those chips get ridiculously hot on these cards...
Re: Difference between USB Legacy Support and Port 60/64 Emulation
Posted on 2020-05-21, 15:58
Port60/64 stuff emulates the hardware of keyboard controller for things that access the hardware directly, even if it doesn't physically exist. I imagine legacy support should do that automatically though there's a chance only the BIOS interrupts are handled without actual hardware emulation in some …
Re: Volo's Gampad to PS/2 Adapter. Device discussion (Do you need this thing?)

I suppose. This only matters for the low button count controllers and would improve their usability though I think there isn't a huge amount of need to support them. I do expect arbitary assignments being possible for the buttons on the controller, making and choosing profile for each particular …
Re: System wide software Equalizer for 9x?
Posted on 2020-05-20, 17:55
With WDM drivers, there's a special filter driver class that could do this stuff but if there's any such thing available for 98SE or ME I don't know. Some Realtek drivers did have an EQ built in their drivers and some Creative cards can do it too.

Tiido, thanks for your input. You really helped with Sega gamepad detection! I think adding buttons to the device would be cheating. The idea is for device to be so seamless - you should be able to forget it's even there! I could sniff keyboard keys, but it's an awful can of worms. I'd prefer not …

You could put some buttons on the device itself.
