Requiring more than 4 megabytes of RAM just to install an operating system (of any kind) is ridiculous. I don't care what Win95 or OS/2 Warp or anyone else requires. If they need at least 8 megs of RAM to run, then that leaves the whole 4-meg market open to us and You-Know-How in the alternative UNIX-like OS segment. We should be able to at least produce a bootable floppy with the CD-ROM that does not have any networking drivers and a minimal set of device drivers. Then, as I suggested a short while ago, the user can pick from a set of customized kernels on the CD-ROM to install permanently on disk. Or leave a full kernel on the floppy, but disable all the drivers and include instructions to the user on re-enabling just the ones that are needed. Will that save on memory usage? Or how about using the 2.0.5 boot floppy image? That works on a 4-meg machine, doesn't it? It shouldn't matter which kernel release is used for installation. -- Brian Tao System Administrator, Internex Online Inc. "Though this be madness, yet there is method in't"
