As far as I know Microsoft provides one basic API call: MessageBeep. It makes a short "beep" (you've probably heard it at some point in your life, right?). That's all it can do. There are no other parameters. Beep. You can't talk to the PC speaker hardware, and Microsoft doesn't care, so that's all …

That's correct. As I understand it, DOSBox was initially developed on Windows where you generally don't write directly to the PC speaker anyway, especially on Windows NT/2000/XP/etc. where user-space isn't allowed to touch any I/O ports. I understand the i/o port restriction in NT windows but it is …

speaker=true enables the emulated PC speaker output, it does not direct DOSBox-X to send port 61h output to the real PC speaker. DOSBox SVN and any other fork behaves the same, even if run under HX-DOS. I've heard there are audio output drivers for HX-DOS, however I don't know how to set that up. …

Can anyone help with a no sound issue running DOSBOX-X DOS port with the HX-DOS extender. The computer is a toshiba netbook which of course has no sound support under dos apart from speaker output. Boots to raw MSDOS 6.22 perfectly and loads doom, wolf3d etc.. perfectly with speaker output for sound …

What type of battery did you use to replace the barrel type ? If the original barrel type was rechargeable through the board then not using a blocking diode on a non-rechargable cell would cause problems with the power to the CMOS chip. Sounds like the CMOS chip was resetting on each boot of the …

First, I would suggest that you use a CF Compact Flash Card to IDE adapter, instead of an SD Card. The reason being, is that a CF card has a direct IDE interface and more reliable than SD memory cards which were not designed to work as IDE disks. EZ-BIOS attempts to create the partitions to the size …

Yes, the Sony PCMCIA floppy drives work with the Libretto without drivers, the BIOS can boot from a PCMICA disk drive. HP and Compaq also work. There's a special key sequence also to update the BIOS from the floppy drive. HOLD F12+POWER ON starts the BIOS update procedure. http://www. …

I think any branded caps would be better for that board considering the state of the ones in the photos. I'd only go for high value quality branded if the voltage rating was above 16V. Low voltage caps like those are not really being stressed too much, so just replace them with as close a value as …

Saved from electrolytic drowning, this very nice Panasonic CF-380 Intel 386 laptop. Kind of reminds of some of those early 90's Tandy laptops and is almost identical to the 1500HD and 2810HD but with a different logic board. Had a no power issue initially, so opened it up and almost all the SMD caps …

I've had success with a 4GB CF card in these machines, anything higher would result in boot issues as you have experienced. Boot with a Win98 floppy then repartition and format the CF disk, reboot with the Win98 boot disk and issue a SYS C: command. Remove the CF disk and using another PC with a …

Sounds like a duff leaking capacitor. Check all caps with a meter. The buzz is mains static hum which is not being filtered correctly.

I've disassembled and repaired many laptops from the 80-90's era and I've found that the majority of these classic laptops/notebooks all have some from of leaking issues with the batteries and capacitors. Sometimes a battery may look fine but on closer inspection if you follow the wires from the …
