Title: PLoP hangs when trying to boot a USB key
Post by: lev on April 12, 2010, 17:04:49 PM
Hi,

I've installed a Linux distro (openSUSE) on a 8 GB Transcend USB key. It boots OK on a recent laptop (whose BIOS allows booting from USB).

To boot it on an older laptop, I made a PLoP bootmanager floppy. The floppy drive is a USB one. PLoP starts OK. Then I plug my key in the other USB port, and hit Ctrl-Shift-U. PLoP detects the Transcend device. Then I hit enter and I'm taken back to the console screen with a bit more than a linefull of periods, with the blinking cursor, and nothing more happens.

FWIW, here's the partition table cfdisk sees on the USB key:
               First       Last
# Type       Sector      Sector   Offset    Length   Filesystem Type (ID) Flag
-- ------- ----------- ----------- ------ ----------- -------------------- ----
1 Primary           0       48194     63       48195 W95 FAT16 (LBA) (0E) Boot
2 Primary       48195     2152709      0     2104515 Linux swap / So (82) None
3 Primary     2152710    15679439      0    13526730 Linux (83)           None

(There are two other views available but I think this one is the most relevant.)

Thanks for your help.

hi,
can you post the "lspci -v" output of the machine?

regards
elmar

Thanks for answering.

The older laptop has no Linux installed. I'll have to boot a rescue system DVD. It might be in a few days, so maybe you could tell me now what kind of info you're after, and other commands to run depending of what lspci will give.

Got it by email... Nice to see you figured it out, that proves I expressed myself well enough to be understood  ;)

:'( My DVD-ROM drive refuses to read the openSUSE install DVD from which I wanted to boot a rescue system. (Booting from CDROM directly via the BIOS menu yields some kind of "bad media" message, and trying to boot via PLoP gives a red "CDROM error".)

Do you know any Linux floppy distro containing lspci? (The few I found up to now only have dmesg.)

Well, I found this which is able to probe PCI devices: Hardware Detection Tool, http://hdt-project.org/wiki . Tell me if it's enough or if you really need Linux's lspci.

I had to copy data by hand, so I wrote down only the parts which looked relevant to me, but still I listed all the devices reported by HDT. (blanks mean I didn't copy the given value, it's not necessarily empty)

Whoo hoo hoooooooooooooo, that works!
I'm posting this from my USB Linux  ;D
BTW, the version that didn't work was 5.0.4-2 (I think I downloaded it a while ago, but only recently had I time to post here).

Thanks a lot!
Cheers,
