i am new to linux
this computer has no boot cd function. i want to install dsl on an empty scsi hard drive connected to a adaptec aic-7870P controller. i tried a boot floppy but the drive isnt detected, so i am thinking i need a module to support the scsi controller, where could i get one?

Assuming such a module exists and is included in DSL, you can boot DSL on a different computer and copy over the appropriate module file to a second floppy disk.

Then you boot DSL in expert mode and insert the floppy and type in the module name when prompted.

Or you can manually hack up the minirt24.gz file and add this module to the loopback filesystem and insmod it from within the startup script.

EDIT: Sorry, I was in Vector Linux modus, so the following does NOT work. Sorry again.

You could try a (scsi) boot diskette from Slackware and the root diskette from Vector. I haven't tried this, so it may not work.

well, i tried getting the adaptec scsi kernel from a slackware cd and dumped everything off the dsl boot floppy onto the c:, then i used loadlin.exe to boot from the scsi kernel and it found the scsi drive and knoppix image. but then it comes up with this:

/modules/cloop.o: unresolved symbol kunmap_high
/modules/cloop.o: unresolved symbol create_bounce
/modules/cloop.o: unresolved symbol highmem_start_page
/modules/cloop.o: unresolved symbol kmap_high

You will need to use the default DSL kernel unless you remaster the entire CD.

It is quite possible that your driver is already included in DSL or in KNOPPIX3.4

What is the exact name and model number of your SCSI controller?

If you don't know, boot up DSL from CD and give us the results of the command:

lspci

(this assumes that it is a PCI based SCSI controller).

cant boot from cd - old computer.

The scsi controller is a Adaptec AIC7870. Its not a PCI "card" but its on the motherboard (same thing).

Try this. Open up an xterminal and type:

sudo su
modprobe aic7xxx

or

sudo su
modprobe aic7xxx_old

and see if it detects anything. You might need to type

dmesg

to see the output of the driver install process.

Or if you can't get that far, boot up DSL on another computer and copy these files over to a floppy disk and then boot dsl on your original computer with the

expert

boot command and insert the floppy and type in the module name when prompted.

The files are located here:

/lib/modules/2.4.24/kernel/drivers/scsi/aic7xxx_old.o

and

/lib/modules/2.4.26/kernel/drivers/scsi/aic7xxx/aic7xxx.o

Good Luck.
