that is  CD-rom.
Ok sorry my mistake!
I took the floppy images off that ISO, from in /install/floppies directory.

[even initial boot fails]


I have a LS120 ATAPI floppydrive connected as a Primary Slave. When I use a (normal 1.44MB) floppy to boot from, my install gets stuck here:
Here you use a floppy  (not the CD rom)
Why the sudden switch for CD to floppy?  (please tell the whole story)

See the above, I really did use the floppy, I took the floppy images off the iso.
The above 'sorry' is accepted  :-)

Insert the root floppy or plug in a USB storage device.
Press Enter when ready, or type a command:
I can press enter all I want, nothing happens!
Tell us more about you computer.  (Has it an USB keyboard?)

It's an ASRock A7VM2 motherboard with an AMD Athlon XP 2200+ processor.
I'm still using the good old PS/2 for keyboard support. No mouse connected.

I have a 40GB 5400rpm Seagate drive attached to my motherboards Primary ATA133 channel as Master. The LS120 ATAPI Floppy drive is attached to my motherobards Primary ATA133 channel as Slave.

I don't have a lspci from the machine, but all of the chipsets on it are Via or Via related (like S3 Savage for the videocard). I know I've got a Via-Rhine as NIC, i'm not sure which revision until I get debian installed.

The machine does have a Via USB 2.0 chipset, providing an ehci and uhci.

PS: If this bug gets resolved, please let me know, I'll do a test run :)

It will also take some effort from you, to get it resolved  8^)

To be honest I think the problem is reasonably simple (though i'm no expert), the installer searches /dev/fd0 and /dev/sda (usb-storage) (maybe /dev/sdb and so on) for the root disk, right? we just need to add /dev/hdb or /dev/hdb1 to that, problem is, it depends on which ata channel the atapi floppy is connected what it's device designation is.

Also the kernel needs ATAPI floppy support compiled into it, or the modules needs to be on the ramdisk for this to work at all. I'm not sure if that currently is the case!

Please note, I'm not a rocket scientist, these are just my two pennies worth... Maybe I'm totally wrong... Maybe not. I hope to hear from you soon,

I think you are too humble  :D

Your analyzis makes sense.
But I doubt that is can be fixed that way.
I see problems in the size of a kernel with IDE code,
as it has to fit on a 1.44Mb floppy (2.88Mb??)

About capacity of floppies:
What fits on a LS120 diskette?
Could it hold a kernel and the initrd?

Geert Stappers
Aha, well, that will fit easily... way easily... A LS120 drive isn't called an LS120 drive for fun ( :p )... It can take 120MB of data. But these disks are fairly hard to come by these days... I don't have any myself, I just use it as a plain floppy drive, it saves cabling and the likes...

But the base IDE code is already included in the current kernels right? so only the ATAPI floppy code would need to be added (and some relatively minor script changes)... I have no clue, how much code/data that would be. ( Don't have any installed systems handy right now. )

PS: Maybe I should just invest 8 euros in a plain ol' floppy drive :s
