Hi i tried installing a huge bunch of unnecessary drivers and stuff into the kernel to see if it would get me through the problem. Now i get VFS: Cannot open device "<NULL>" or unknown-block(8.2) Please append a correct "root=" boot option; here are the available partitions: 1600 4194302 hdc driver: ide-cdrom 0800 8192 sda driver: sd is this a step in the right or in the wrong direction? i haven't changed my config files since last time.

The hardware in the host, except for the CPU, isn't seen by a guest machine. IIRC, all versions of VMWare, when using an 'IDE drive', look like an old PIIX4 chipset.
