Zenith Data Systems ROM BIOS

I have a portable Zenith Data Systems computer, Model # ZFA-121-52 and Serial Number 508EE0351. It looks like pictures of a Z160 but I don't see that ID anywhere on the machine. Unfortunately, the BIOS has been removed and having one in place will most likely help the performance of the machine a lot :). If anyone has one of these machines, I would appreciate it if you could send me a binary image of the two BIOS chips. I don't know what is available in the CP/M world but there is a utility called HACKROM in the MS-DOS world that will make a copy of the BIOS chip(s) and store it on disk. I have used it and it has saved me a LOT of trouble in the past when I had a machine with a BIOS that would go bad as soon as it warmed up. Got a listing while the machine was still cold, blew another set of BIOS chips, and I was back in business! Since this is an MS-DOS machine, it will probably work to get a good copy of the BIOS.
