syslinux does not interpret backslash

Post #1 of 5 (2710 views)

Hello list,

while I managed to install syslinux and have it boot,
there seems to be
a problem with interpreting filenames. It looks for
files in /boot but
at the same time does not realize that the "/" is not
part of the
filename. It prompts me with boot: then every filename
I type is set to
2 characters "." 3 characters i.e vmlinuz would appear
as vm.lin. To me
it looks like syslinux uses /boot/ as part of the
filename here ( 6
characters )

Not sure whether I am missing something here, or
whether this migh be a
subtle bug.

The stick is 1GB ha one partition set by parted
(msdos) and formatted
with mkfs.vfat, then initialized with syslinux
/dev/xyz

Thanks for any helpful insight,

Casual

I would go for the first option.

insight is allways helpfull.

Where I do my best, I'm completely lost by the above message.

For me is a backslash the \ character.
Backslash is in the subject line, but nowhere in the message body.

> It prompts me with boot: then every filename I type

At the boot prompt has a LABEL to be typed.

The syslinux website says at http://syslinux.zytor.com/faq.php

| Since version 3.32 label names are no longer mangled into DOS
| format (for SYSLINUX.)

Could a syslinux from before 3.32 used?

So only less then 5% of the capacity of the stick is used.
I would go for EXTLINUX and use to full gigabyte.

Thanks for the fast reply,

Alas I got confused here, please read "backslash" as
"slash"

Good point, I will check that.

Actually not, with FAT32 the full capacity is
available.

I tried it with the current version of syslinux (3.61-pre2), and I
cannot reproduce this failure.

Thank you, hpa,

I was using the openSuSE supplied rpm which is at
3.31-76. Considering
your and rest of lists feedback, I decided to make it
myself as well as
switch to EXTLINUX. It seems that with EXTLINUX I can
boot some hitherto
unusable sticks with 2048 byte sectors.

Thanks for providing this useful project.
