P965 Neo JMicron ?buggy? in PATA-mode and cannot install newest driver

Question

I have a MSI P965 Neo and a PATA HDD (alone on the IDE-cable)
if I copy some big files over network (via onboard realtek) from 2 other computers in my network:
PATA:
a) files are ok (correct md5), without the JMicron-driver 1.06.01.00 from MSI website, but very slow speed and laggy mouse.
b) files are NOT ok, with JMicron-driver 1.06.01.00, speed is fast, mouse are ok.
if I use a PATA-2-SATA adapter from a friend and the HDD is
a) hooked on JMicron-SATA-Port, with JMicron-driver 1.06.01.00, files are ok.
b) hooked on intel-port, files are ok.
I did some tests with a dlink-NIC on msi mobo, but in PATA-mode on JMicron still errors.
so for the JMicron in PATA-mode there is a bug, in SATA-mode not.
I have hope with with the new driver from MSI site vesion 1.14.00.00 but this one won´t install - got a dialog with "updatedriverforplugandplaydevices: error".
any help ? coz I cannot use the PATA-2-SATA adapter from my friend forever and buying one isn´t a big deal but I paid already for not 100% bugfree msi p965 neo.
update:
filecopy from internal hdd to external usb-hdd, is not a problem, only over network. so JMicron in PATA-mode produces errors if realtek-onboard-chip is under load or an other NIC.
OS was WinXP SP2 32bit, but WinXP x64 has the same problem.
I tried also older realtek drivers but no success.
but Vista RC1 has no errors with filecopy over network with jmicron in pata-mode, with Vista´s default drivers for JMicron and realtek-nic

Answer 1

I got the same problem with "HANGING"... the whole system freezes (mouse and sound for example) when I access my DVD burner, e.g. wenn I insert a new DVD, and/or copy a file like VTS_04_1.VOB to my system (just for testing). I never experienced this behaviour in any PC system before... This isn't acceptable on a 2 gig, 6600 core 2 duo system.
I played World of Warcraft recently, and burned a video DVD from a hdd image file at the same time - which should be blindfoldly managed on a core 2 duo 6600.
on my old system (an amd, single core) the same action would have no effect on the game. But on my new MSI board system, there were major hangs to the game... Just when the system accessed the DVD burner.
More strange appears to me, that accessing the second DVD device, the DVD-R (just reading) doesn't cause any hangs to my system.
I never had any of this occurences in any PC before ... This must have something to do with the Jmicron IDE to SATA2 "bridge".
I got the JMB36X 1.14.01.exe and the latest BIOS
My system specifications read as follows:
1x 3R Systems DCase R202, silver be quiet
1x SilentMaxx 480Watts, 19dB extra silent
1x MSI P965 Neo-F Socket775, FSB800/1066 ATX PCI-E16x
2x CSX1024MB DDR2 DIMM, 800MHz, original Value
1x Core 2 Duo E6600 (2,4GHz 4MB), Box S775
1x GeForce 7900 GTX 512 MB Gigabyte, TV-Out/DVI Retail
2x SATA2 250GB Samsung SP2504C
1x LG GSA-H20L Black Lightscribe, Retail Nero+Kabel
1x Lite-ON DVD-ROM SHD-16H5S-05C, 16X
Hoping there will be a fix soon... I noticed this strange behaviour at once, when I installed Heroes of Might and Magic V (just after I bought my new system) and wondered, why the installation routine takes SOOOO long and consumes one core cpu completely....
