RESTORE_NVRAM and SAVE_NVRAM
A.1
Save NVRAM data in EEROM/TOY to a floppy file.
Save the system NVRAM data from 8KB EEROM and last 50 TOY
RAM bytes onto a write-UN-locked FAT formatted floppy to a file. By
default, if no script argument is specified, all NVRAM is saved to file
ALLNVRAM.SAV. If the file already exists, then a copy of the original file
is made to *.BAK. If that file exists, it is overwritten. Note, attempts to
write to a write-locked floppy fail silently.
Syntax
save_nvram
{all,arc,srm,toy}
Arguments
group
Specifies the group of NVRAM data to be saved. One of the following:
•
all : All of the 8KB EEROM and 50 bytes of TOY RAM are saved in
file allnvram.sav. This is the default, if no argument is specified.
•
arc : ARC (AlphaBIOS) data in first 6KB of the 8KB EEROM is saved
in file arcnvram.sav.
•
srm : SRM console data in last 2KB of the 8KB EEROM is saved in
file srmnvram.sav.
•
toy : TOY console data in the 50 bytes of TOY RAM is saved in file
toynvram.sav.
Examples

...and enter "y" and press
