Install CD for versions 1.1a and 1.2 will not boot from SCSI CD Rom drive with 
Adaptec 2940 U2W controller

The machine in question is an all SCSI system (specs follow at the bottom of 
the message), IDE controllers are turned off. I have no problem booting other 
cds on this system. Also, booting the Gentoo disk on one of my other (IDE 
based) systems works just fine. 

What happens is the following:
during boot the SCSI detection finds my devices and gives the following 
message: 
" 
A BOOTABLE CD-ROM IS DETECTED IN YOUR CD-ROM DRIVE... 
The boot sections on your bootable CD-ROM are: 
0. DEFAULT ENTRY 
" 
then a message saying something about SCSI setup successfully then it 
continues to boot from the HARDDISK... 

I've tried changing the boot settings in the motherboard and SCSI bios, 
however this did not make any difference.

I've tried version 1.2 ix86, 1,2 i686, 1.1a ix86 all ISO images. I've burned 
the cds with Nero 5.5.6.4, cdrwin 4.0A, fireburner 2.1.7, all cds have the 
same problem. 

To work around this problem I did the following:

- turned on IDE 
- installed a IDE cd rom drive
- set all IDE bios settings to AUTO 

now its booting from the Gentoo install CD

After modprobing the right modules for the scsi hardware, I took the same CD 
out of the IDE CDrom drive and used it in the SCSI cdrom drive for the 
remainder of the install. 

seems to me that the bootimage on the gentoo cd has a hard time booting from 
divices hooked up to an Adaptec 2940 U2W SCSI card (or maybe more SCSI cards?) 


system specs: 
ASUS K7M 500 -U 
AMD Athlon 600 
Adaptec 2940 U2W Bios version 2.20.0 
Pioneer DVD ROM DVD-305 
192 MB ram pc 100
Matrox G400 max 32 MB

Can you try this with the new live cd?

I have the same problem here with the 1.4rc1 cd (UT version). Burned it 
with some Nero 5.5.X.X (could look it up if you think thats a factor). My 
Adaptec 2940U2W finds the disk as bootable, but boots from first scsi disk 
even if I have cdrom as first, second, and third boot-device in my bios. As 
a workaround, I disconnected the scsi-disks during controller scan, and 
hotplugged (yeah, I know that this IS risky) them when gentoo started 
without the scsi-disks present. Then all worked fine, even with my normal 
boot-priority (floppy, cdrom, scsidisk). I would gladly give you any 
system-information if that could help.
Timo
PS: Just noticed that I have the same controller on a K7 system as the 
other guy... will lookup the bios-version asap and upgrade to newest, if 
you think that helps

I filed that bug again for gentoo 1.4rc1 as bug 11275

i've tried it now with AHA-2940AU 
and Plextor 40-TSI

it works fine, even if i disable the onboard IDE

is this a onboard controller ?

Please try the "2002122100" or later livecd from
http://www.gentoo.org/dyn/experimental/livecd/ and post your results here.
Comment 6 Timo Boettcher 2002-12-24 05:04:17 UTC
Do you really want two separate bugs on this? I think 

http://bugs.gentoo.org/show_bug.cgi?id=11275
is pretty much the same.

Anyway, I 
just tested livecd-basic-x86-2002122100.iso, with same same result: Disc being detected as 
bootable, and then my grub popping up.

I get the strong feeling that somehow I am the one who has 
the bug... (pebcak)
What should I check to cut out any possibiity of that?
Comment 7 Daniel Robbins (RETIRED) gentoo-dev 2003-09-09 15:28:01 UTC
Timo, this really sounds like a BIOS issue. Have you tried 1.4 final? Any luck?
Comment 8 Andrew Cooks (RETIRED) gentoo-dev 2003-11-25 07:38:14 UTC
Please try the latest LiveCD and reopen this bug if the problem persists.
Comment 9 Chris Gianelloni (RETIRED) gentoo-dev 2005-03-25 11:25:08 UTC
Moving these so we can remove the "Install CD" component from "Gentoo Linux".

I apologize to everyone for this spam, but according to the bugzilla developers,
this is the only reasonable way to do this.
