i'm a newbie. After browsing this forum i decided to upgrade the firmware of my philips dvdrw824p (p.2.2) to benq dw822a b3cl-2 (for d/l support). after that, my windows xp sp2 didn't boot (stopped during windows logo screen or even before with a blank screen). the only way to make it boot is to go to bios and disable the secondary slave drive (where my philips is attached). strangely to say, after that, system boots up and even recognize the dvdrw drive (as atapi dvd dual 8x4x12) but it behaves not as expected: it's slower than before (with dvd+r, the only media i use), sometimes it stops and refuse to go further, and morever sometimes system won't boot up (i have to try several times).
so question is: is it normal? if not, how can i fix it? or how can i restore to original firmware (2.2.)?
