IDE/DMA/VIA chipset question (compiling new kernel)
Before anything else, I'd like to thank the people who have helped
me before. This has been really nice... And so far, support here in
this list has been really efficient. Thank you all.
Ok - now, to my little problem:
I have a Pentium II 400Mh with 64Mb RAM; my motherboard and HD both
support DMA/66, the CD-rom drive also supports DMA/33.
I'm running potato now, and I've compiled a new kernel
(2.3.47), optimized for my box... But at a certain point when
running make xconfig I had one doubt...
According to the help box, I shouldn't choose to "use DMA by default
when available" is I have a VIA VP2 chipset. Well, I have a VIA
693/596 chipset in my motherboard (which has 2 PCI IDE interfaces
on-board)... And I don't know if my chipset would be somehow
"related" or "derived" from the VP2, or whatever... In short, I
don't know if it's safe to use DMA by default... So I've compiled it
Now... My questions are:
1) How much difference would that option make?
2) Would it be safe to compile the kernel with that option?
Thanks a lot!
