Scsi 2940U2W AIC7895 boot problems v2.0.36

Tue Jan 12 12:20:07 PST 1999

Hello all,
	Didn't know who to send this to so I sent it to those listed.
        See the attachments also.

	I'm having problems booting my new Dell 333mhz Optiplex GX1 that
has an Adaptec 2940U/UW Dual Channel Scsi card with a Western Digital
9.1Gig -1807A4 hard drive. Presently on booting Linux it hangs and
never sees the Hard drive.

System Configuration:
  Dell 333mhz Optiplex GX1
  2940U/UW Dual Channel SCSI with an AIC-7895 chipset.
  Western Digital 9.1 Gig hard drive.

BIOS:
  Phoenix Technologies Bios
  Adaptec Scsi Bios v1.33S2 copyright 1997. Note: the S means special

Hard Drive Partitioning:
   c:\   MSDOS 6.22 as a 2Gig FAT & Win95
   d:\   NT4.0 service patch 3 as 2Gig FAT
   e:\   MSDOS 6.22 as a 2Gig FAT & no Win95
   f:\   MSDOS 6.22 as a 2Gig FAT & no Win95
   h:\   MSDOS 6.22 as the remaining Gigs and FAT & no Win95

Linux Configuration:
   a). Linux 2.0.36 with the gcc patch applied. 

	*** see attached
           file m1.config for the configuration used to compile Linux
	***
   b). Linux kernel compiled with only
		- floppy drive, 
		- mouse,
       		- AIC scsi support, 
		- loop device with Ramdisk and initrd support,
       		- and a few network card devices.
	        - compiled with module support but no modules loaded.
                   All hardware stuff is compiled into the kernel.
    c). Compiled with GCC 2.90.29 980515 (egcs v1.0.3)
    d). Linux booted as DosLinux which resides on top of the DOS
        filesystem. Upon reboot, a menu comes up with NT and MSDOS
        as menu selections.
    e). Linux made as the BzImage kernel.

Method used to run Linux.
    a). After rebooting and the SCSI Bios detecting the Hard drive
        on SCSI ID=0 Lun=0 as a western Digital HD, then
    b). Selected MSDOS from the menu selection that permits NT4.0 or
        MSDOS to be booted into.
    c). After seeing the MSDOS prompt, cd'd to the c:\doslinux\setup
        diretory and ran setup.bat (came with DOSLINUX) and other
        stuff. I just copied the bzImage created earlier and put
 	it into the kernel subdirectory and changed the batch files
         to load the kernel. The setup.bat file loads the bzImage
        using the file system image on initrd as "ro" using loadlin.
	The hardware device is "loop".
     d). The Linux kernel starts to boot and gets as far as the
         SCSI 2940 adapter and then hangs thereafter. The boot sequence
 	 never timesout to tell me that the SCSI software didn't see
 	 any Scsi devices (ids) or didn't understand the Hard Drive
	 configuration used to recognize it. Perhaps this needs
	 to be added to the software.
     f). The only way to get control back is to do a reboot.

Notes:
    i. This problem occurs the same way when using DOSLINUX70-75 versions
       whereby they use the loop device instead of umsdos now and it is
       also built using kernel v2.1.132

    ii. This problem occurs the same way when using DOSLINUX70-75 versions
        but the kernel image was generated using Linux v2.0.36+patch for
        gcc by recompiling.

     iii. The new kernel image based on Linux v2.0.36 was compiled with
          module support but no hardware drivers were compiled
          as a module - including the scsi drivers.

      iv. When DOSLINUX70-75 (the new version) along with Linux2.0.36
          are put on my old 100mhz no-name brand PC that has IDE disk
          drive - 1.2Gig Quantum - it will boot without any problem.
          Hence Linux v2.1.132 and v2.0.36 with IDE Hard drives works
          on an old PC: with scsi support on my new PC with scsi doesn't
          boot.

       v. Since I'm using DosLinux and the MSDOS partition with Linux
          residing on top of it, I don't think that NT4.0 is causing
          my problems since it isn't seen by Linux. Moreover, Linux
          doesn't have multiple disk support compiled in and should
          therefore only see my partition on drive C:\ and shouldn't
          see the other drives D-H.

  Please see my attachments,
       a). file m1.config, the configuration used to compile Linux v2.0.36
       b). file scsiboot.txt, the boot sequence at the point it then
           hangs after seeing the scsi adapter but not the disk drive.

	TIA.
