Description Isaac Salsberg 2001-07-10 18:36:18 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

Description of problem:
I installed red-hat 7.1 on a scsi jazz drive, attahced to a VAIO lap-top 
using the Adaptec APA 1480 CardBus. The installation went just fine. 

I did not install lilo, so I generated a boot disk in order to boot linux. 
When I tried to boot, the system hangs saying:

Loading aic7xxx module
/lib/aic7xxx.o: init_module: No such Device
Hint: insmod errors ca be caused ...
ERROR: /bin/insmod exited abnormall!
VFS: Cannot open root device "sda2" or 08:02


How reproducible:
Always

Steps to Reproduce:
1. Insert boot disk
2. See messages
	

Additional info:
I used the following parameters at boot time, but did no work:
PCMCIA=yes iobase=0x140

Comment 1 Isaac Salsberg 2001-07-11 23:12:01 UTC

I finally could boot using a floppy disk, however the network card never worked.

I tried using the pcinitrd utility but it generates such a hugh image 
(initrd.img) that does not fit together with the vmlinuz file in the floppy,
so I found a workaround doing this:

# mkbootdisk 2.2.14-5.0
# cd /tmp
# mkdir qq
# mcopy a:initrd.img
# gunzip -c initrd.img > tempo
# mount -o loop -t ext2 tempo qq
# cd qq
# vi linuxrc, so it looks like this:


#!/bin/nash

echo "Loading pcmcia module"
insmod /lib/pcmcia/pcmcia_core.o
insmod /lib/pcmcia/yenta_socket.o
insmod /lib/pcmcia/ds.o
/bin/cardmgr
insmod /lib/pcmcia/cb_enabler.o
insmod /lib/pcmcia/pcnet_cs.o
echo "Loading scsi_mod module"
insmod /lib/scsi_mod.o
echo "Loading sd_mod module"
insmod /lib/sd_mod.o
echo "Loading aic7xxx module"
insmod /lib/aic7xxx.o
~

Afterwards:

# cd lib
# mkdir pcmcia
# cp <modules-path>/pcmcia/pcmcia_core.o pcmcia
# cp <modules-path>/pcmcia/yenta_socket.o pcmcia
# cp <modules-path>/pcmcia/ds.o pcmcia
# cp <module-path>/scsi/scsi_mod.o .
# cp <module-path>/scsi/sd_mod.o .
# cp <module-path>/scsi/aic7xxx.o  .

Then I copied the other files as th linuxrc file says.

# cd /tmp
# umount tempo
# gzip -c temp > initrd.img
# mcopy initrd.img a:

Then I used that floppy and boot linux.

The scsi modules and aic7xxx load just fine, however I could not loas 
cardmgr and the network card modules because they need other libraries that
do not fit into the floppy.

So, it was a partial solution. Still is necessary to startup the network card, 
but for that the pcinitr utility should be improved.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
