Question installation difficulties, SONY vaio C1XS, external CDROM not recognized


I am a complete novice to Linux. Tried installing Slackware 10, SuSE 8, and Fedora Core 2 but no luck.

SONY C1XS has an external PCMCIA CD-ROM that gets recognized by BIOS and starts the installation, but then as soon as the kernel loads, it looses it and cannot find the install source. Tried all 3 linux verions I have and no luck with either one of them.

Please, help!!! How do I find the PCMCIA driver and how do I use it to recognize (mount?) my CDROM? PS. I have and external diskette USB drive...
?????

I have a sony vaio z505 with an external cdrom which connects through the pcmcia port. The first thing I should say about the drive is it's a total piece of junk.

Now that I've got that off my chest here's a workaround that worked with mandrake 10 allowing me to install on my laptop. Boot off the mandrake 10 install cd-1 and as soon as you see the first screen hit F1 which will take you to a boot prompt. At the boot prompt, type the following and then hit the Enter key:

linux nopcmcia ide2=0x180,0x386

While this worked for mdk10 it did not work for mdk9.2 so make sure you use mdk10. The trick also works with most versions of knoppix except at the boot prompt you should change "linux" to "knoppix".

This is a failrly well known "cheat code" to get pcmcia cd drives working in linux for an install and I've seen it posted in various forms in several places. Sometimes it works; sometimes it doesn't but it should work for you with mandrake 10.

thanks a lot. Got Mandrake 10 and started loading with the switches as you said but another problem on my C1XS is that it has a weird screen resolution 1024x480native (terrible thing that is!) and the setup GUI that mandrake loads extends beyond its limits.

Any idea how to force it to 1024x480 or maybe 640x480, so i could at least see the prompts?I tried adding 'resolution=640x480' at the command prompt, after the rest of the swithces, but that didn't work...Maybe I shoud try some other linux version, besides Mandrake...

The switch you want is "vgalo":

linux nopcmcia ide2=0x180,0x386 vgalo

and if that doesn't work, try:

linux nopcmcia ide2=0x180,0x386 text

This last one will put you in "text mode" but it's really an ncurses version of the graphical install program.

As to other linux distros, give it a shot with:

<kernel name> nopcmcia ide2=0x180,0x386

The kernel name is usually "linux" but not always. Per my above post, in knoppix it's "knoppix". And how you get to a boot prompt will vary from distro to distro but most have some way to get you to a boot prompt so you can pass boot options. Check the distro documentation re passing boot options.

ok, all working fine now! THanks a lot!

the command that worked was:
vgalo nopcmcia ide2=0x180,0x386 (with Mandrake 10)
without any mention of 'linux' as a kernel name. i tried
linux nopcmcia ide2=0x180,0x386 vgalo
but that defaults to normal resolution... so i guess vgalo is not a switch but an alternative kernel name...
Again, thanks much for your help!
