I found the following code in boot/sys.c (-current). Which goes a long way in explaining
why I can't boot from my third IDE disk (Secondary Master):
if (*cp >= '0' && *cp <= '9')
if ((unit = *cp++ - '0') > 1) {
printf("Bad unit\n");
return 1;
}
I'm at a loss as to why the code checks for the character pointed at by cp to
be within the range 0-9, inclusive, and then after decoding it decides to limit
the range to 0 or 1??
You don't get "Bad unit", if you specify 'x' instead of 0-9.
Is there a problem with using 2 or 3 in the boot line: "wd(2,a)/netbsd"
I was pretty sure I had this working on a previous version of NetBSD (maybe it was
FreeBSD or BSDI???).
I thought I'd ask before changing the "> 1" to "> 9". Just incase there is some
really bad thing that can happen. Suggestions, comments, actual knowledge
are appreciated.
Thanks,
Paul
