Hi there,
I've been struggling with these settings for YEARS! I've read what I can find about it and for the most part I've managed to get good results, but I'm wondering if anyone would take the time to explain HOW mask and maxtransfer can be determined? Calculated?
I see a LOT of threads asking for help regarding settings for a particular system, and the most common reply is "check the manual, most products have the settings there" but I don't own a single SCSI/IDE-kontroller that has these settings in the manual (except perhaps the GVP HC series II, but it's kind of cryptic). It seems that many members on the forums are able to just calculate, or figure out good values, but I've never understood how thats done.
It has to do with memory adressing? The MASK represents which segment of the memory should be used for DMA? And maxtransfer represents how many bytes can be moved at once? Yeah, I don't know? And I would GREATLY appreciate it if someone took the time to give a proper explenation, or link to one (something might have gone under the radar). How technical is it? Is it really as difficult to understand as it seems?
