Dear Everybody (incl. Ms., Mrs., Mr., Dr., Prof., ETC.)!
After one week trial I decided to bother you with my problem:
I recently bought a GA-586DX dual Pentium PCI-ISA Mainboard with built in Adaptec AIC-7880 PCI-to UltraSCSI Host Adapter.
I try to put both DOS and Linux on the 4.1 Gbyte Quantum wide SCSI harddrive.
What happens:
First of all, Linux does not seem to detect the SCSI devices (well known scis: 0host messge)
After specifying Autodetect and looking for AHA-294x family drivers it founds it and sees the disk. Can be partitioned etc.
However at the end of the installation can't create the boot image.
I've tried to install Red-Hat 4.1 and 4.2.
Finally put a good old 200 Mbyte IDE harddisk into the machine as well (going back to Flintstones...) and managed to put Linux on that in 5 minutes.
The boot sector for Linux is now the boot sector of /dev/hda.
There are three partitions on the big SCSI harddisk (/dev/sda):
1 Gbyte DOS primary on /dev/sda1
1.5 Gbyte DOS extended on /dev/sda2(5)
1.5 Gbyte Linux on /dev/sda3
The Linux native partition (83) created on the SCSI harddisk works fine.
But I can't properly mount the DOS partition under Linux.
Linux mounts it, sees it, but a simple cd command creates a SCSI queu full and SCSI reset. After that it works again. I could cp files from the DOS partition to the Linux partition.
I believe the problem is with partitioning, but simple rules (like create both DOS and Linux system partition in the first 1024 ) don't solve the problem.
When I partitioned the SCSI harddisk fully under Linux (including the partitions for the DOS) everything was fine, LILO could be configured, but the DOS boot was gone. Could not find the system.
Playing around with DOS's fdisk /mbr and similar trials made no difference.
When I partitioned the DOS part using DOS's fdisk, Linux's fdisk complained afterwards and LILO install reported invalid partitioning for /dev/sda1.
I can't see any more variation. :-)
Has anybody had a similar experience?
Does anybody know the solution?
I would be very grateful to hear your suggestions.
