433.0. "TOS 1.4 booted from harddisk ?." by UTRTSC::BRANCH_ADAM (nothing is impossible......) Tue Mar 21 1989 07:59
Hello all,
Is there somebody out there who tried to do same as i did,
ie. booting TOS 1.4 directly from harddisk.
I wrote a little program in assembler which is started from the
auto folder on harddisk partition C.
It then loads a patched version of the tos.img file.
The patch includes the removal of the relocation part in the startup code.
Which is $100 bytes long.
The relocation is then done by the loader program which relocates
the code to address $AD00.
Then tos 1.4 is started at address $AD00.
But before the relocation starts I have to set the Supervisor mode
and the interrupt level to 7 to disable the uninitialized interrupts.
However at this moment no debugger program can keep control of the
process.
I think it is during the relocation that the system traps through
`illegal command` vector and the systems hangs hopeless.
Does anybody have an idea how to solve this problem, or managed
to do same as i want to do in another way ??.
Regards,
Arthur.

| I'VE GOT A PATCH.
THIS PATCH FOR THE DISKVERSION OF THE TOS 1.4 MAKES IT POSSIBLE
TO BOOT THE TOS.IMG FILE FROM HARDDISK.
I THINK IT IS PUBLIC DOMAIN, BUT I'M NOT SHURE.
