Hello,
concerning the failure to load stage2 i made the following discovery:
1. the old binary distribution works well, even if i compile it myself from the
source
I downloaded the cvs version using the date option for every day since Oct. 1.
The results are:
2. beginning with Oct. 20, it does not work anymore -> The error has to do with
APM, since this was introduced or modified on Oct. 20.
3. the version 19, 18, ... x (where x is not yet known - i did not test this
all out yet) do only work, if my ZIP-Drive is not installed in my computer. I
have no idea why this happens.
Future debug plans:
1. I'll get the latest release now and will try it.
2. I'll insert more printf's ...

I tried that. To no avail. :-(

I inserted DEBUG_PRINTs into cmain in stage2.c. The message is not printed and
it's right at the beginning. I did not look at init_bios_info in common.c yet.
However, since the message in cmain is not printed, I assume stage1 is faulty.
Now, what modifications where made to that part after the LAST (not the
current) release? Maybe i should mention my system configuration:
Abit BP6 motherboard, 128MB RAM, 2 Celeron 466, EIDE Hard disk, SCSI-Controller
By the way: The disks work in my other computers, i.e. grub boots ok there.
Any ideas? Volker
