I can't install Windows 98 on a KT6V-LSR

Question

I used to be able to dual boot Win98 and 2K from different partitions on a single 80Gb hard drive. Needed the Win98 only because my old Matrox capture card has no drivers for the newer OS’s. When I changed my mobo to an MSI KT6V-LSR (Via KT600) I couldn’t get the Win98 partition to work (I didn’t have to wipe it through 2 earlier mobo changes. I guess it couldn’t stand the 3rd)
The previous setup was like this, all on a 1-1/2 year old 80gb Maxtor:
Primary partition, 753 mb, FAT32, Windows 98
1st logical partition, 11gb, NTFS, Windows 2K Pro
2nd logical partition, 25gb, FAT32, for video files
3rd logical partition, 40gb, FAT32, for all my data, downloads, etc
I could get the standard Windows OS selection page upon boot. This time whenever I try to install Windows 98 I get the above “serious error” message right after the partition check by scandisk. It's not the installer's fault, it's been with me for a long time. Worked flawlessly before.
I am able to install Win2K on NTFS or FAT32. It is only when I try to install Win98 that I get slammed with this error. I can’t use my capture card and that’s where I earn a little.
The drive passes both the Maxtor diagnostic software (full system scan) and the Seatools generic test (full system scan).
There are no viruses detected (my software may be faulty, though).
PartitionMagic 7 fails to create the small partition I need for Win98, saying “cannot create partition, anti-virus software may be running” But I have disabled any virus settings in BIOS and I am using PartitionMagic from the boot diskettes.
Really stumped here. Can’t afford to buy a new drive right now just so to transfer my files and wipe the current drive.
In summary, the drive allows me to install Win2K on either NTFS or FAT32. But it will not allow me to install Win 98, whether on a Primary partition or the first logical partition (i.e. after Win2K has already been installed)
I have since been able to install Win98. But I had to connect the Drive to a Promise Ultra66 IDE controller.
Question is, is the new hardware really incompatible with the old OS?
THEN...  On two consecutive nights, my registry in Windows 2000 got corrupted (hive corruption). And I have had to reformat and reinstall both times. I am worried now that the mobo I got may have serious faults.
Hope you can give me quick feedback on this.

Hello,
You should be able to use windows 98 with this motherboard.
Can you try this.
Format the drive with only 1 partition (80GB FAT32)
Use maxblast to do this.
Remove the Ultra ATA66 PCI controller.
Remove the sound card.
Plug the hard drive in IDE cable 1 (set it to master too)
Plug your CD drive to IDE cable 2, set it to master.
Reset your CMOS
Now when you power up, enter the BIOS
go to Frequency/voltage control
Set the CPU to 166Mhz FSB (it should be running at 1.667Ghz)
CPU Ratio = Auto
go to advanced chipset configuration >DRAM settings
Set the memory to 333Mhz(166Mhz)
Go to Standard CMOS setup.
Press on your Hard drive
Set the mode to LBA
Also change your boot order to
Floppy
CD ROM
Your hard drive
Go to integrated peripherals
Disable the onboard sound
Now save and exit.
Boot from the windows 98 CD
See what happens.
