ATA questions

[charlener]

I was putting together a computer with athlon 1 gig and fic az11e board and noticed that both the 12x burner and the 12x dvd always showed up as ata/33 in the bios (before loading the os). Is this the normal rate? or should it be at something like ata/66? I never noticed with my own computer, which happens to say mode 4 or something, but I'm having trouble with both dvd playback and burning on this new computer. could this be the reason?

that is normal rate for CD-ROMS and DVD players. to my knowledge there are no ATA66 CD-ROM's on the market yet. how are the 2 CD-ROMS hooked up? i have seen where some DVD players have troubles with UDMA being enabled. try disabling DMA for one of the CD-ROM drives and see if that fixes your trouble. if you have the 2 daisy chaned only the master can run in DMA mode and not the slave. let me know if this helps you.

ahhh...well, I had both enabled DMA, cdrw being sec master and the dvd sec slave...the dvd's yucky playback if not dma and the burner really needs it to cut down on errors...it's a sony spressa 12x and a toshiba 12x m1402...if I put on on primary could I use dma for both then?

where is your hard drive running from? you only have 2 IDE connectors right? you can only run 2 masters and 2 slaves.

I only have two ide channels, but if I put, say, the cdrw on primary slave and dvd as sec master could I enable dma on both?

 

[hclarkjr]

no, you can only enable UDMA on master channel only for each channel
