f1gp: hd installation and assign..

[jolly11]

hello to everyone
I've an amiga 600 with HD and only 1mb ram.
many games don't work, because the lacks of ram, one of these is f1gp. from the disk 4 of this game
Auto-booting the game from Disk #2 (or clicking on the 'Formula
One Grand Prix' icon on Disk #2 from the Workbench) will start the
simulation without the animations and scrolling credits (the 'front-end')
for a faster startup.
Note for hard disk users with restricted memory: If you have
SUCCESSFULLY installed the game to hard disk but find that it wont run
correctly (the front-end doesn't run, or the game fails to load after
the front-end) then you are probably running short of memory. Grand
Prix requires about 356K of free, un-fragmented CHIP ram and an
additional 456K of ram of any type (also unfragmented).If you only have
1 MB of ram in total then presence of Workbench, any external drives and
even your hard disk itself can reduce the memory available to the system
to below this threshold. You might only be short of CHIP ram, in which
case :-
From the CLI issue the following commands (assuming that you
have the new copy you just made in DF0: )
protect df0:s/startup-sequence rwed
copy c:assign df0:
iii. Use a text-editor to place the following two lines at the start
of the startup-sequence file (i.e. ABOVE the "Formula One Grand
Prix" line) in the 's' directory on this disk (assuming that
you chose DH0:GrandPrix as the install-to-hard-disk destination)
assign f1gp_disk_#3: dh0:grandprix
assign f1gp_disk_#4: dh0:grandprix
iv. Write-protect the disk and boot from it.

but I can't make it work (assign error returncode 10). f1gp installed itself in SYS:grandprix. I've 2 partitions, called Work and System2.0 (f1gp it's here).
so, how to make it work?
thanks
