[N8VEM: 16631] zeta sysgen to ram drive?

[Jim Strickland]

I'm a CP/M newbie, so this is probably old hat to everyone else. I noticed that the boot rom gives me the option to boot to my ram drive, but when I attempt to sysgen the ramdrive, sysgen complains that drive A does not have reserved tracks. What am I missing here?

Basically, it is saying "You can't do that". There is no place to put the
system.
Putting it on the ram drive is kind of a waste of time and resources. It
would be the same code as in the ROM.

The QP/M installer, which I was interested in booting off the ramdisk (since my floppy system doesn't work yet) requires Sysgen. Plus, if you can't sysgen the ramdisk, why offer it in the bootloader options? -JRS

Why would I want to do that? Well, the QP/M installer, which I was interested in booting off the ramdisk (since my floppy system doesn't work yet) requires Sysgen. Plus, if you can't sysgen the ramdisk, why offer it in the bootloader options?

Booting from the rom is a standard way on N8VEM or Zeta.

For what it is worth, I have always considered the RAM disk to be temporary
storage. Since it is fairly small, I didn't want to reserve space for a
system image. Although Zeta is built to preserve RAM contents, it is not
the usual configuration for the other N8VEM variants, so I did not really
consider it a viable place for a system image. I realize it probably is a
good way to sue Zeta and will consider making it possible for this reason.

Yes, you are absolutely right that it is confusing to see it offered as an
option in the boot loader when it is not possible. It is this way because
I leverage a temporary copy of the OS to perform the boot load and I did
not want to assume drive mappings at that point (A: could be mapped to a
real drive at that point). The boot loader is on my list for a complete
overhaul.

Thanks,

Wayne

Ahh, okay, thanks. I thought I was missing some step in formatting or something. No worries. Thanks.
