RE: Bootable CD Problems

[Dan Harrison]

Hi,

Am really interested in having a go at doing this myself.

Can you point me to a readme or faq to get me started ...
I'm afriad not. I couldn't find anything about the topic; I had to 
invent most of it by just knowing how the startup process works, and 
how to burn bootable images.

If I can make headway, I may try and do an article or something, but 
for now there isn't anything out there I can find.

Sorry.

Re: Bootable CD Problems

[Dan Harrison]

 Well it depends on how you've done the bootable CD.
 I havent played with one since about 4.6.2, but I believe someone 
portedthe LIVECD-1.2 to english from portugues which would 
have made things easier. The MFSROOT is specified in the kernel you 
put on the CD,   so it depends what you have it set as, and how 
you've stored your information on the CD.

 I always had problems trying to compile the MFSROOT into the kernel itself
 so hacked it around by loading the file system in through the boot loader
 instead.
That's interesting. Do you remember how you did it?

 So depends how you've built it, and what/where its failing.
I can't really tell; that's the problem. As I said before, it says 
Mount root file system from cd9660:acd0 and then hangs without any 
more messages. I read the things another guy posted which apparently 
is evidence for a buffer overrun or something like that, but I'm not 
sure.

 Id recommend just grabbing the LiveCD stuff Fugspbr made. It worked fairly
 simply for me, though track down the english version, as I know there is one
 around somewhere. http://www.fugspbr.org is the original Brasilians that made
 a liveCD building script.
I went to the site, and they sent me to their archives. I found a 
link to sourceforge, but I can't read any of it. Are you sure there 
is an English version anymore?

Anyway, I would like to know how you loaded the filesystem in through 
the boot loader if you could tell me; this may be a solution for me.

Hi,

I posted a mail regarding the installation of 4.8-release a while ago. I
tried to install 5.1-release and got i running - the error occurred, still.
Where 4.8 just hung, 5.1 did manage to give me some more info: the problem
is ATA timeouts for my CD. This seemed to be a problem for many ppl out
there, and not once I came by aworking answer.

At boot time, after probing the HDs, its time for the CD, but it hangs for a
while, then following error messages start to appear. They appear anything
from 10 to 30 times before the computer boots up.

acd0: read data overrun 34/0
acd0: MODE_SENSE_BIG command timeout - resetting
ata1: resetting devices... done

This problem seemed to come along 4.6RC2, and it's errdata sure has it
mentioned. The fixes there did not work on my computer, thou. I have tried
to play with sysctl and device.hints, and dis/enabling UDMA support in BIOS,
adjusting cables etc.,  all in vain. The problem seems to be with particular
CDROM brands, as one older Toshiba worked fine.

Should I make a bug report out of this? It seems like a big problem to many,
without any fixes. Is it a bug in the driver?

My computer is a MSI6330(KT133) mainboard, 30Gb UDMA100 HD as primary disk
in ata0-master,
10 Gb UDMA66 slave in ata0-slave where FreeBSD resides (master has Win98 and
FreeBSD boot manager),
and HP CD-Writer 8200i CD-RW in ata1-master. When adjusting the device.hints
I got FreeBSD to get it as UDMA33, as it should.

I don't need the CD in FreeBSD (but it wouldn't hurt to have it either), so
the only harm in this is that the booting takes forever. I don't want to
disable anything from BIOS, because I use it in Windows, and I don't want to
restrict it's use/efficiency.
Any thoughts appreciated.

I recall having the same or, from somewhat vague memory, similar problem
some time ago. It was about the time when CD drives started being commonly
installed as master on the secondary port instead of as a slave. At that
time
moving the CD to slave fixed the problem.

But then it might not work with the current round of difficulties.

Subject: 4.8 Install Failure


 Hello everybody,

 I just tried to install new 4.8 FreeBSD from ISO images. But it still ends
 with following:

 acd0: READ_TOC command timeout-resetting
 acd0: resetting devices...done
 acd0: read data overrun 12/0

 I have Compaq Pentium PRO, 200 MHz with 64 MB RAM, with Symbios Logic
53C875
 SCSI adapter and Compaq ST32171W HDD (2 GB), with Compaq Neteligent 10/100
 TX PCI UTP and 3Com590 NICs, Matrox MGA Millenium.
 My installation still end during probing all devices...

 There is no ATA HDD, CD was connected first as Cable Select, after install
 failure as Primary Master, after install failure replaced with another
 CD-ROM unit with same results.

 PC normally boots from this CD, but then install fails.

 What is the problem and how can I solve it ?

 PLEASE HELP..

I think, nobody in FreeBSD team is working on this problem. Of course, there
is so many work on whole system, that such small problem is not so
interesting. And, may be, they do not know about it.

That's all, best regards to all FreeBSD funs.

 Hello Dan,
 
 you are the fourth person except me, who has this problem and wrote it to
 the list. FreeBSD is still doing nothing with it - is it such big problem
to
 solve it ? There is no useful advice yet, what can we do - nobody knows ?
 
 Peter Rosa

 If you're saying it's a bug in the system that a bootable CD won't
 mount, that's lousy.

 If you're making a general remark about the lack of information on
 the topic, I'll keep trying.

 If you're saying something else, please elaborate.

Subject: Bootable CD Problems


 Hello.

 I'm trying to build a bootable BSD 4.8 CD. Nothing fancy, just a
 shell and maybe a few utilities, but I have a specific problem.

 Whenever I boot from the CD, the computer asks for the root
 filesystem. I point it toward the CD (cd9660:acd0), but it hangs on
 Mounting root from cd9660:acd0 My guess is that it can't find
 the mfsroot file. So, I tried all the possibilities: a zipped and
 unzipped file, upper and lower case filename, upper and lower case
 listing in /boot/loader.conf, and nothign worked. Does anyone know
 the proper way the mfsroot file should be done, or another problem
 that could be causing this?

 I have /sbin/init on the disk, and rc didn't load; I inserted 'echo
 rc loaded.' into the rc file, and didn't get any messages.

 Any help would be nice, and I wil answer what questions I can about this.
