I have tried, to replace the boot message “Hit Esc for .altboot” of an floppy at QNX RTP 6.1 .
I have tried several options, but i can’t change the message.
E.g. dinit -f test.ifs -m “test.” /dev/fd0
If I change the message via the spatch utility, it works.
In the online help of dinit stand, that the message can be up to 30 characters.
But if I change more than 20 chars (the original message is 20 chars long), the
floppy don’t boot.
‘dinit -m’ doesn’t work in QNX RTP 6.1. Try latest version of QNX or use spatch 
Your message can’t be longer than 20 chars and should be trailing 0x00 at the end of string. Probably, 30 chars long message and -m option were intended in 6.1 but not realized.
Hello ed1k,
Try latest version of QNX or use spatch
First I have used QNX 6.2.1 NC.
Then I recognized, that I can’t use the following things in the newest version:
Then I downdated to QNX RTP 6.1.
Why they have removed all these good stuff from the actually NC version ?
That are very interesting parts of QNX, I remember the “Incredible 1.44 MB Floppy Disk” with
QNX, Photon, Voyager …
keep on remembering !
i used to hand this ‘incredible’ floppy to my friends and now the entire gang experiences sleepless nights while digging deeper and deeper into qnx.
such a great stuff. i am talking seriously now !!
