This place is a wealth of info.
As you guess, i also have a problem.
I have tried searching for answers but can’t find what i’m looking for - and i’m relatively new to burning.
I read that DMA is better than PIO? Anyway, if i do enable DMA on for HD it stuffs up windows after i restart and i end up reintstalling windows. This happened twice long time ago.
I there is no DMA option for my acer50x and my sony40x12x48 in Device Properties. And i get burn speeds of around 18x on 40x rated media (TDK).
Gig.Tech. i440BX (havent updated BIOS tho),
SB PCI 64,
Windows95 with OSR udate + the IDE update suggested by a moderator.
I installed the sony drive on a win98, celeron 633, Gig.Tech. i810e but there was still no option for DMA.
