Again Message-ID: <imgidataD9oq4q.18y@netcom.com> Organization: NETCOM On-line Communication Services (408 261-4700 guest) X-Newsreader: TIN [version 1.2 PL1] Date: Mon, 5 Jun 1995 05:34:02 GMT Lines: 59 Sender: imgidata@netcom8.netcom.com A while back I posted a query about "Invalid format!" messages at boot time from trying to load a PPP enabled kernel. I've since looked into the source code and discovered the following things: 1. I found that "Invalid format!" is a response to the kernel having an invalid magic number. I looked in the kernel that I'm trying to boot, and the magic number was identical to the default kernel. 2. In utter frustration, I reinstalled from scratch. From the response to my prior question, I attempted to work around what may be a hardware problem by changing from: Partition Cyl Start Size Type Mount a 0 25 Mb newfs / b 3000-ish 32 Mb swap swap c FreeBSD slice d Entire Disk e 6000-ish 435Mb newfs /usr to: Partition Cyl Start Size Type Mount a 4000-ish 25 Mb newfs / b 0 32 Mb swap swap c FreeBSD slice d Entire Disk e 6000-ish 435Mb newfs /usr and that resulted in not being able to find *any* kernel. If I typed '?' at the boot prompt, I got ". .." as the entire result. I also tried: Partition Cyl Start Size Type Mount a 4000-ish 460Mb newfs / b 0 32 Mb swap swap c FreeBSD slice d Entire Disk and that didn't work either. 3. I went back to the original partitions, and immediately after installing, I made a copy of 'kernel', set the same permissions and did a chflags (per the 'make install' steps). When rebooting, I got the 'Invalid format!' message for the kernel copy, and the original kernel booted fine. Help!
