I guess I never spelled it out in the body of the message, but like the Subject line says, these are definately scd-device proprietary Sonys. > If it's attached to a proprietary card, the address is usually set by > jumpers on the card. I received some help from someone who knew something about the cards. However, I could not get this second machine to work. According to his recollection, of the four sets of jumpers on the card, JP4 specifies where in the range 0x300 to 0x3f0 the card responds. However, the fact the GENERIC default is 0x230 seems to indicate otherwise. Plus, the machine that did respond at 0x340 was unjumpered on JP4. (Both the machine I have got to work and the one that does not only had position 2 of JP1 jumpered. The off-list helper indicated that JP1 dealt with DMA.) I have been unable to track down on-line docs about these cards. Sony's website has DOS/Win drivers for these old things, but nothing I could find about jumper configs. Any pointers to docs or further direct help would be much appreciated. > Hope you can work around Y2K on that thing or you're going to have a big > doorstop in 6 months :-) Uh-oh... Dare I ask? What Y2k thing? I can always pull the CDROM. It's not absolutely essential. -- Crist J.
