nForce2 + Ultra DMA 2 = IDE driver problems, good results!

Recommended Posts

This is not related to CD BurnerXP but it is related to burning CDs, so I thought it might be useful to a few of you and generally a good source of info for the MANY people who have this problem (i've been googling my butt off trying to work this out and founds lots of people have the same problems). This kind of thing is hard for a noob like me to work out and even harder to think up the right words to stick in a search engine to get useful info on, so here goes.

CD-RW LTR-48125W Secondary Master on Gigabyte Motherboard GA-7N400 pro 2 (PCB rev 2.0)

Driver NVIDIA nForce 2 ATA Controller (v2.5) 5.10.2600.415 built by: WinDDK

Best nForce2 IDE Driver settings, NVIDIA multi word 2 using NVIDIA drivers, NOT ultra-dma and NOT pio and NOT standard windows IDE drivers. Tested on Gigabyte GA7n400pro2 rev2.0 (BIOS version FH), Liteon LTR-48125W CDRW on secondary master IDE, Pioneer DVD-115 ROM on Secondary slave IDE(UDMA 2 seems to work fine for it, must be a bug in write modes or just Liteon/Plextor related bugs), 1024 meg 333mhz DDR RAM (2x256 meg + 1x512 meg), Geforce 2 MX AGP card, 80GIG seagateIV HDD on Primary IDE, SCSI controller in PCI (disabled), Firewire/SATA/RAID/Serial/Parrallel/Gameport/MIDI disabled in BIOS.

All testing info follows...

Yes, I have been trying to work this stuff out for the last 3 days and finally narrowed it down to driver settings and did some tests. Okay a lot of tests...

CD burn "test writes" with buffer underrun enabled for 650meg data on 700meg cheap LASER "premium quality" 52x cdr which ONLY allows 32x, (Smart Burn sensing the quality). Also a DVD-rom as Secondary Slave in UMDA mode2. Primary Master is a Seagate Baracuda IV 80 gig hard drive at Ultra DMA 5 - Ultra 100 (bios auto select on). Firewire, SerialATA, Serial Port1&2, Parallel Port, Gameport, Midi, LAN Rom boot - ALL DISABLED IN BIOS. Also have a SCSI card in a PCI slot which is disabled.

Changed the settings on the drive and rebooted for every test. UDMA2 has been tested HEAPS in various configurations and has never worked on this motherboard under any program or win98 or shipped and latest BIOS version FH or gigabyte vendor drivers or NVIDIA drivers or windows drivers.

nVidia IDE drivers,

PIO barely works at ave 12x speed and heavy cpu use (a bit better than windows driver)

Multi-word DMA 0 works, didn't check time

Multi-word DMA 1 works, 32x took 2:48

Multi-word DMA 2 works, 32x took 2:49

Ultra DMA 0 failed, 0% constant spinning getting faster and faster up to speeds i've never even heard it reach before! argh she's gonna blow capn'. In NERO it starts at about 7% and locks up the program so you can't stop the drive, RecordNow also locks up like Nero. CD Burner XP at least eventually will report a failure.

Ultra DMA 1 SAYS it works but it really does not. It takes 10 seconds and thinks it worked. I do not know if it will work in real non-test mode but I am assuming it will fail.

Ultra DMA 2 - Ultra 33 fails, 0% constant spinning getting faster and faster up to speeds i've never even heard it reach before! argh she's gonna blow capn'. In NERO it starts at about 7% and locks up the program so you can't stop the drive, RecordNow also locks up like Nero. CD Burner XP at least eventually will report a failure.

Then I uninstalled the NVIDIA nforce2 IDE drivers and rebooted then chose Standard Dual Channel PCI IDE Controller driver when it asked for drivers. After every detected hardware item it asked to reboot, which I didn't do - there were about 6 devices so this would have really sucked if I did reboot every time it asked... Hope this isn't wrong, funny that it didn't ask to reboot after the final device was installed (secondary IDE for the curios) . I checked the device settings before reboot because I was curios and noticed the CD-ROMs were PIO, so I changed them to "DMA if available" then rebooted finally.

Standard windows IDE drivers

"DMA if Available" failed with a similar error as usual but with more info, IDE/SCSI reset. Failed at 0% and took a long time to stop and report the error.

"PIO Only" Mode worked, 32x took 7:31 with a LOT of speed changes and heavy CPU use which made the mouse pointer jerky and generally sucked all round.

Then swapped to NVIDIA NForce2 SPP/IGP ATA Controller drivers version 5.10.2600.340 built by WinDDK

Ultra DMA 2 - Ultra33 failed at 0%, same as others just keeps spinning.

Multi-word DMA 2 worked, 32x took 2:48 and about 4% CPU

PIO mode barely worked, 32x took 5:50, MASSIVE cpu use.

assume UDMA1/UDMA0/DMA1/DMA0 same as other nvidia driver results

Best nForce2 IDE Driver settings, NVIDIA multi word 2 using NVIDIA drivers, NOT ultra-dma and NOT pio and NOT standard windows IDE drivers. Tested on Gigabyte GA7n400pro2 rev2.0 (BIOS version FH), Liteon LTR-48125W CDRW on secondary master IDE, Pioneer DVD-115 ROM on Secondary slave IDE, 1024 meg 333mhz DDR RAM (2x256 meg + 1x512 meg), Geforce 2 MX AGP card, 80GIG seagateIV HDD on Primary IDE, SCSI controller in PCI (disabled), Firewire/SATA/RAID/Serial/Parrallel/Gameport/MIDI disabled in BIOS.

PS: this software rocks, I have been using Nero for years and tried a few others before trying somethin "FREE!!" and OMG.. awesome. F&^%K the rest this is the best "Value".

Redoo reported me once, that uninstalling nfoce drivers did work and it didn't work when they were installed. Well, I think it is different with every PC configuration.

if someone can tell me how to reliably remove the nforce drivers I will test the Windows drivers again, I tried Uninstalling and also directly changing drivers in device manager.

I'm pretty sure it will give the same results.
