Hi everyone !

It seems i'm running into the same problems with a Yamaha YMF754 inside this time a very small and cute Sony PCG-C1VE.
I tried everything we said or experimented before on this post Problems with a YMF754 inside a Toshiba Tecra 8200 but nothing works good this time.

The soundchip is a YMF754-R :

In the BIOS, there is nothing about changing IRQ of the YMF :

Under DOS, if i use the SETUPDS modified for ICH2, or any SETUPDS i have for different southbridges, i have the same result exactly :

The YMF754 is using by default IRQ9 :

The southbridge seems to be an Intel PIIX4E/M :

Under Windows 98SE, i used some default VDM drivers and it sounded great. Still, i tried these VXD drivers but the sound doesn't works, just a strange noise on the left speaker :

Hi all,

I will try the drivers i found on this other thread :
No sound using Yamaha YMF744/754 VXD drivers under Windows 98SE (Sony PCG-C1XN) (SOLVED !)

Still, under DOS mode it will not be working. I may look on the YMF7x4 thread on Vogons about modifying a SETUPDS.EXE to make it works with my chipset 😒

I don't know what kind of program you are using, but it writes YMF754B and then DS-1S in one line, it's impossible, since DS-1S is YMF744:

Did you tried to manually change the IRQ to 5 in Windows?

As for DOS usage I don't really know if the integrated northbridge of the Transmeta Crusoe are capable to do DDMA. Can you give us the full output from PCI.EXE to see which PCI IDs it uses?

Oooh, this system is based on a Transmeta Crusoe CPU? That's a fascinating little processor. 😃 I haven't had the opportunity to play with one myself, but you should definitely hold on to it. It might become even more of a collector's item than it already is.
