notFred vs. free ESX is not saving configuration

[petcherd]

I just got a couple of serious workstations that will not be employed for real work until their project is ready. When life hands you Shoffners, fold!
2 @ Xeon X5472 with 16 GB of RAM

I figured the fastest way to get them folding was to install VMWare ESXi v3.5 (you know, the latest freely downloadable ESX), and then run VMWare vCenter Converter twice to install notFred's VM with 4 CPUs and 8 GB of RAM.

It sorta' worked, but the VMs are not saving their configuration or checkpoint files, probably because ESX has converted their ATAPI virtual disks to SCSI... /dev/hda1 became /dev/sda1.

Does anyone have a good clue how I can fix this?
