I'm trying to install DSL 3.1 on a 64Mb CompactFlash card (to be used on a Compaq IA-1).

I have a generic USB-based Memory Card Reader/Writer (supports CF, SD, Memory Stick, etc) that is automatically recognized by Ubuntu 6.1 but NOT by DSL 3.1.

How do I get DSL to recognize and mount the Memory Card Reader?

Something from /dev goes in /etc/mtab along with its file structure type (I assume "vfat") and then another entry is made in /etc/fstab ... I'm a Linux newbie so I humbly request your patience.

Hi DSL Guy!

I don't think it will work with DSL. I have a similar device that only is for CF-cards and that one works fine and mounts as sda1 just like a usb-stick. I had read that multiple card readers didn't work with DSL that's why I bought one only for CF-cards.

Have fun,
meo

OK, thanks for clearing that up. So my Memory Card reader is unusable with DSL. Let's try this another way.

The Memory Card Reader is recognized by Ubuntu and WinXP. In theory, I can write a bootable DSL image directly to the CompactFlash card using either Ubuntu or WinXP.

I can use Linux's "dd" and in WinXP I can use
"physdiskwrite" (a non-native utility).

The big question is: Can I get a bootable (frugal) DSL image?
Alternately: How do I make a bootable (frugal) DSL image?

Or am I all mixed up and there's a really simple way to copy the DSL files onto the CF card?

This may not work with a Compaq IA-1, but...

I just now performed a USB-HDD install of DSL-3.1 onto a
512MB Compact Flash card in a multi-card reader. Make sure
that the multi-card reader and CF card are plugged in BEFORE
booting your DSL-3.1 CD and try this:

Apps > Tools > Install to USB Pendrive > For USB-HDD Pendrive

With my hardware, the device was "sda". Here is part of the
dialog from the install script:

Display your USB storage device information log? (Y/n):
scsi2 : SCSI emulation for USB Mass Storage devices
Vendor: ICSI Model: IC1210 CF Rev: 1.4F
Type: Direct-Access ANSI SCSI revision: 02

SCSI device sda: 1000944 512-byte hdwr sectors (512 MB)
Enter the device name of pendrive.(EXAMPLE: sda): sda

My PC can even boot from the CF card!

My ASRock 939DUAL-VSTA motherboard is ali1695 based,
so DSL doesn't recognize most of the hardware on it, but
Fedora Core 5 shows this:

FC5 shows the CF card as sdb because FC5 recognizes a
SATA disk as sda, but DSL doesn't see the SATA disk.

DSL-3.1 only recognizes the CF slot of the multi-card reader,
so it probably depends on which slot is the first slot of your
multi-card reader.

Is that because DSL-3.1 cannot access multiple LUN's?

Unfortunately, DSL 3.1 does not "see" any of the four slots of the Memory Card Reader and the device (with CompactFlash card) is plugged in prior to booting DSL. In WinXP it is seen as four separate drives (E-H) and the CF slot is the second drive (F).

DSL 3.1 does recognize my USB flashdrive and identifies it as device sda but it does not do this for the Memory Card Reader.

I agree DSL's USB-HDD install would be the way to go with the CF card. I've done this with my USB flashdrive and it boots and operates perfectly.

So here's the next Big Question:
Can I copy the DSL image from the USB flashdrive directly to the CompactFlash card?

and as a follow-up:
Is it the right image to use if the CF card will be seen as a "hard-disk" in the target computer (CF card is connected via IDE on the Compaq IA-1)?

Ubuntu recognizes the Memory Card Reader and the USB flashdrive. I should be able to copy the DSL image directly from the USB flashdrive to the CF card with dd. Does this sound viable?
