Did you disable onboard IDE and set IRQ14 to Legacy ISA?

Wing Commander is more a benchmark for graphics card speed than for CPU speed.

Nothing, but it's the official way.

What about all the page faults, TLB clears, disk access emulations and whatnot that paging brings with it opposed to direct memory access 😀

A two-character string can't be THAT hard to decrypt. HunterZ should have learned the hard way 😉

The games might not have to swap out memory though.

Re: GUS and DosBox questions

I couldn't get my real GUS to work with the downloaded Daggerfall. Digital playback was "bubbling"/stuttering in the sound test. Worked with a SB Pro. MIDI won't initialize, neither with nor without ultramid loaded. I couldn't start the game as it didn't like my self-made CD.

hs3_h: The column does not show, as expected (Hercules, as CGA, uses the MC6845 which seems to add the display address to the row counter directly) [Side hint: Hercules 3bah, check for bit7=0 for vertical retrace instead of bit3=1] hs3 EGA: One EGA card shows that column, the other doesn't. …

Install the game from within DOSBox and keep the mountings if you didn't.

About Ghostbusters: Depends if the Tandy uses IRQ5 as vertical retrace interrupt. So what type of Tandy does DOSBox emulate? :) From RBIL: the Tandy 1000, 1000A, and 1000HD use IRQ2 for the hard disk; the 1000EX, HX, RLX, RLX-HD, RLX-B, RLX-HD-B use IRQ5 instead; the 1000RL, RL-HD, SL, SL/2, TL, TL …

It showed on S3, ET4000, TVGA8900. I don't think I need to try more 😉. On the VGA card the display address is applied to the display address comparator only once in a frame, at the start of the vertical retrace pulse. For CGA I didn't tinker to find out when exactly it happens yet.

It's really just limiting the voltage at the cell. With a regulated power supply: Set the voltage to 4.20V and the current to a value the cell can cope with (less current if it was discharged below a certain voltage level). And hope the supply doesn't break and put out more than that voltage.
Re: A very special question about old 486 CMOS batteries
Posted on 2009-07-08, 18:26
The NI* cells are charged with constant current and unlimited voltage. The cell itself keeps the voltage low. The litium cell requires a limited voltage. It is possible that with a load the voltage will not rise as high as 4.65V but you'd have to check. If this was my board I'd add another diode to …

Ok, now I've found something. The left column of asterisks also shows up on real hardware VGA but not on real hardware CGA as in DOSBox. The "slow reaction of scroll" I can't repoduce neither in vgaonly nor others.
