How to boot a PC diskless and Netless connection?

PC's aren't designed to boot NETLESS and DISKLESS. You can do one or the other, but not both. You need an imbedded solution to do that, one where the operating system is booted from ROM. -Michael

Do you mean 'Floppy' Diskless or 'Harddrive' Diskless? As Michael says, you cannot do both. I have a slave PC with 5¼" & 3½" Floppies and 250MB ZIP Drive that I use in my Internet Cafe as Disk Reader/Writer for customers. (it also acts as a Anti-Virus checker) As a backup it has a small (40MB) Harddrive to boot with when required. Perhaps a solution like this in one way or other may help in your needs.

There is a very easy solution. Get a Commodore 64. the OS is built right on the chip!

What are you trying to do? I have experimented with a diskless workstation. I found the easiest thing for me to do was to put an on off switch on the hard drive and turn it off. But you can do this to get, say, a ramdrive with bulletin board software on it that stands alone; 1. Make a boot floppy with a ramdrive and cd-rom support. If you have no switch off hard drive, you make a CD-ROM with whatever you plan to run on it. This you xcopy to the ramdrive each time you start the station. The problem with this is that I have never found any internet software that will load from a ramdrive, so this is limited to running bulletin board type software. (And it probably does not fit the exact difinition of a diskless workstation)

Of course it is possible to boot an IBM PC architecture without disks or network connection. Ideal for remote, high vibration/dusty environments eg. vehicles. There are many DOS ROM solutions out there for extremely stable, small and simple single-tasking "embedded" PCs eg. Datalight. Then what ? You've booted. Where's the app you are going to run ? Are you going to stick that in ROM/SDRAM "diskless" memory too ?
