No real details. (This from a fussy old fart (me) who wrote boot-time initialization code for VMS on the VaxFT3000). Still, it is consistent with normal bootstrap processing. I still think having a tertiary boostrap would do work fine, and the tertiary bootstrap itself would need be not much larger than the secondary bootstrap, and would need only a 64 KB buffer, and could be placed in low memory... Leaving a full 3MB for the kernel itself... You would need as many of these as you had secondary bootstraps. One for each boot method... And the nice thing is you would only use it for compressed kernels, and it would require no changes to the kernel *or* the secondary bootstrap (except for changing the default bootfile). ----------------------------------------------------------------------------- Robert Withrow, Tel: +1 617 598 4480, Fax: +1 617 598 4430 Net: witr@rwwa.COM R.W.
