Hi,

I'm trying to install Linux 2.1 on a pentium 120 with 64MB RAM and 3 2 Gigs
scsi hard drives.
Before I describe the problem here is the hardware description:

- The scsi controller is a 16-Bit High performance ISA SCSI Controller
(TMC-1650/1660/1670/1680) from Future Domain.
- The hard drives are Quantume_Empire 2100s 2 Gigs hardrive.
- The BIOS is a SCSI ROM BIOS for 18C30/18C50/1800 version 3.6.

First step in installing linux is creating a boot disk with the bootdisk
image. The boot disk image I used is the SCSINET1.GZ. So I booted the computer
with the boot disk and got a "boot:" prompt. I press enter to see if it could
recognize the SCSI controller, but it could not, I got the message "SCSI: 0
hosts". So I used force harware detection and at the "boot:" prompt I entered
the following: ramdisk tmc16xx=0xca00,11. Still, it could not find the SCSI
controller. So I tried the "ramdisk tmc8xx=0xca00,11" and I got the message:
SCSI: TMC-8XX/TMC950
SCSI: 1 host
First problem is how can I get a message saying that is recognizing the SCSI
controller as a TMC 950 if it is a TMC 1650.
But anyway, I tried to create a linux partition using the following:
fdisk /dev/sda
I got a message that it could not open the device.

I would appreciate any help on this problem. How can I make the boot recognize
the SCSI controller and the 3 SCSI hard disks.

Thank You,

Tom Techoueyres

Judging from a quick look at the driver, it looks like it scans all valid
addresses for the card, so you shouldn't have to pass parameters to the
kernel. However, it also looks like the driver (as of kernel 1.1.95)
only supports up to bios version 3.5, so it may not like the signature
it finds with your 3.6 bios. If you know a little about drivers, you
could possibly patch it to work, fairly easily. If you value your time
very highly, though, it would probably be more cost effective to just
spend about $100 (or even less) for a PCI host adapter that is supported,
and would give you considerably better performance, anyway.

That driver may be very forgiving on its scan.
