I was using Softick RAMDrive before the 1.21 update.
after installing new firmware (1.21) it causes endless reset loop.
it must be about the change in nvfs.

I've tried Palm Ramdisk now and it gets the same behaviour.

When I install anyone of these 2 softwares I go into an endless reset loop.

Becareful if you are using RAMDrive; don't restore it from backup after new update.

I don't think PalmOne would fix this in future fw releases...
