Knoppix 7.05 flash install - drive not recognised by BIOS

[jonbanjo]

Thanks. I just checked my laptop with an OpenSuse USB install and that is recognised and boots OK. So both my computers that can't see Knoppix USB install for booting can boot from USB.

As for age, the laptop is getting on a bit and perhaps there still could be some age issues with it but the motherboard in the other PC is only 1 year old and now has a BIOS that's only 1 month old.

Thanks for the CD boot suggestion. I'm sure that would work but really I'm looking for a persistent (btw, OpenSUSE fails on that for me - works fine just live but my quad core PC seems to grind to a halt with the overlay...) USB drive that would work on most PCs I come across without the need to have a CD and (as things stand and perhaps I'm just unlucky with what I have here to try) a 2/3 failure rate is not too encouraging for that.

Are there any differences in the type of USBflash media between the ones that work and those that don't?

I've got one PC whose BIOS requires only an adjustment in the boot priority sequence to boot from US UNLESS the flash media is over a certain size, in that case, it appears in the disk menu of the BIOS too, and has to be configured there as well, or it won't boot. That same BIOS also eliminates USB from boot priority list (and the disk list) whenever you boot without a USB storage device installed. I then have to reset the BIOS before booting the next time I want to boot from USB.

I just installed 705 to usbflash yesterday BTW, hoping it would be able to read my 64GB SDXC card on usb30. Unfortunately, it couldn't. But strangely it could read it in the laptop's internal SD slot, although at only 10MB/s.

I've been using the same USB drives for OpenSuse and Knoppix. The problem has followed Knoppix.

As for the size. The first partition for OpenSuse was 670Mb. The Knoppix ones I looked at were 4.02Gb for a DVD install and 14.93Gb for a CD install so there was quite a difference there.

Anyway, I created a 700Mb FAT partition on a drive and installed the Knoppix CD version on to that.

This drive will boot on my laptop. I can't get it to show on my desktop though.
