YSL, hi there.
Naturally I do not have the Japanese manual but there is no similar reference to MWDMA in my English version. Not to worry.
OK, now the good news. After 6 weeks of brain-ache I have discovered how to fix this problem, albeit due to the efforts of one man. Am I happy? Indeed. (that’s an understatement, but I’m tired)
Now then YSL, I have just successfully burned 15 CD-RWs and 5 DVD+RWs without a break. I have used an assortment of files. All the way from thousands of small font files right up to huge zip files of several hundred MBs in size.
The result? Not one glitch, ANYWHERE!!!
OK, my setup at the moment has my 712A set to ‘cable select’ connected to my secondary IDE (it has never before worked reliably on the primary and secondary IDE channels). There are no other drives on this channel.
It is set to ‘cable select’ due to an earlier failed attempt to fix the lock-up problem so I will try it as ‘master’ later on. I am getting very good quality burns when using q-check for both C1/C2 and PI/PO errors. I have used Nero to verify all recorded data with no problems.
To cut a long story short YSL you need to install the “PCI Latency” patch for VIA chipsets by George Breese. See here for more info:-
The file is 0.20b21 (updated 6/21/03) :-
George states that the file will fix in addition to other things problems when ‘copying to or from an IDE DVD, CDROM, or CDRW drive.’ Of particular interest to you YSL is this:-
‘Beta testers say that this version is stable on the Asus A7V133 motherboard (KT133A chipset), as long as CPU cooling is not enabled by software.’
Anyway, give it a try YSL and let me know how you get on. I know it may seem risky using this beta software but I’ve had no problems so far and my hard drive performace has increased too (tested with HD Tach 3.0)
Oh yeah, I’m currently using VIA Hyperion 4-in-1 drivers (version 4.51) with everything installed. OS is XP Pro with Service Pack 1. I’ve been burning in Nero (latest version) which before now would give me frequent coasters. As would PlexTools and Alchohol 120%.
I’ll be back later to see how you do.
Boy am I happy!
Good luck, Kremmen.
