[Trlog] Help! SBDVP and HP Laptop

[Denny Sahovic]

I did not get any positive response for DOS drivers for AC97. I had the same
problem looking for a DOS driver for NeoMagic 256AV for my laptop. Just
because of that I have to run TR in a DOS Window (only for phone) to borrow
Win98's sound drivers.

Just as Brian, VE7JKZ, and few other people here, I have a problem of being
able to play F10 message, but could not record. In my case, file is created
(or F10 overwritten), but with 0 length. On few other computers (desktops
with ISA Creative Labs SB) recording and playback is perfect from DOS6.22.

This problem has been posted, even before, by few laptop users. I could not
find the definite answer. Is it something that PnP cards do to DMA? Could it
be the problem with built in a conflict between built-in MIC on a laptop and
MIC-IN line? Or is it something in a Windows mixer setting, that doesn't
work in DOS window? I tried downloadind Yamaha DOS mixer, and I saw all the
settings for BLASTER, WSS.

I tried few different Laptops (NeoMagic, Yamaha) and ended up with the same
recording problem. As for running pure DOS setup, you have to be lucky to
find DOS drivers for the laptop soundcard.
