Hi Elmar,

Back in April I posted here about USB-stick booting problems and you solved them. Thanks again for that.

In the course of that thread, I had noticed that I couldn't boot from a Live DVD in my laptop's internal DVD drive (http://forum.plop.at/index.php/topic,191.msg1642.html#msg1642). I finally found why: the drive dates back to when DVD+/-R(W) didn't exist, and it can read DVD-ROM only. Good reason not to boot from DVD-R  ;D

For a few months I've been looking for an internal DVD+/-RW burner to replace my DVD-ROM reader. But new ones are really expensive (over 100 $), and used ones compatible to my laptop are rare (and expensive also, around 50 €).

So, now I consider buying an external burner and attaching it through a PCMCIA port card (my builtin USB ports are 1.1, which I find too slow for DVD operation). There are three kinds of such PCMCIA cards providing either: USB 2.0, firewire, or SATA.

I thought "maybe one of these kinds will be 'transparent' to the BIOS and let me boot from the BIOS menu. Who could know this?". And immediately I answered "Elmar of course!"  ::)  (Then I went here and saw you were just developping USB-through-PCMCIA, curious coincidence!)

Now, sorry for all the verbiage :P and here are my questions:
- is there a chance that an external SATA DVD drive connected through PCMCIA will be operated transparently by my old BIOS?
- same for firewire? USB?
- if not, is there a chance that in the next few months you'll make Plop Bootmanager handle optical drives connected to PCMCIA via USB/firewire/SATA? (I saw in the status blog that you began working on USB CD drives in november and had some success.)

Thanks in advance.

Best regards,
Lucas

hi,

i don't think that your old bios will provide booting from any device connected through pcmcia. but i don't know it 100%.

- if not, is there a chance that in the next few months you'll make Plop Bootmanager handle optical drives connected to PCMCIA via USB/firewire/SATA? (I saw in the status blog that you began working on USB CD drives in november and had some success.)

yes, the chances are good that i finish/restart the optical usb device stuff. maybe i press it into the 5.0.11 release. but its not fix. it depends on the troubles with the usb cdrom driver

however, in your case, i would buy an usb pccard and no firewire or sata. i think, with the usb pccard you are more flexible. the usb pccard will also speed up booting from the usb thumb drive or usb hard disk. i am using the PCMCIA Controller DELOCK 4 port USB, ArtNr. 61234. but any other usb pccard should work too.

best regards

Thanks for the ultra-fast answer!

You make good points here. After all, since I will seldom boot from DVD (I do need it badly, but not frequently), speed is not a primer; and when burning, slower is said to yield more reliable media (deeper/wider pits or in whatever way "better").
