I love MenuetOS. I want to embed menuet on a portion of the ram so the computer can boot from there. this will give me a real time system without hard disk n no floppy drive. How easy will it be n can i get some hints?? How can a portion of my normal ram be made to store it instead of the diskette?? Exclamation I really need ideas. thanx all of u in advance.

There is no way with your normal RAM. The normal RAM is volatile, the information stored on it disappears when power goes down.
What you want can be accomplished using a EEPROM to replace the normal ROM (not very convenient for an OS under continuous developement)

Other idea is to use flash memory as part of the RAM, but I don't know how easy is to manage it given the existing PC architecture. I wonder why notebook makers doesn't do that yet.

Hm, maybe it is possible, using free EPROM boot chip on the LAN cards. You know, most LAN cards have one free socket that is namely for EPROM chip, programmed in the way to provide boot using network instead of hard disk. Maybe it is possible to program this chip with small enough OS and to reach tottaly disk-less boot? btw: the most of the flash ROMs have pins compatible with the pins of the EPROM memories.

Of course it is possible to be created special ISA or PCI card containing as many as you need chips of EPROM or FLASH that to contain the OS.

Also I am pretty sure, some APPLE models have OS instaled on EPROMs.

Regards.

How about using USB-memory?

no, i am not using USB memory, but it will be good for movable environment.

Yeah, you should really implement the boot from usb function, cause' there will be usb in all machines, and it could replace a boot from floppy.

I think there is menuet code already written to boot from network.

This could be modified to read the rom / ram chip on the card.

I may have this archived but it also may still be out there somewhere.

Does anyone remember where this is?

I'll look around here. Later, Mark
