I see, I hadn't thought of using the loopback device. If you come up
with something let me know. Off hand I don't see how this would work but

Well, that depends on the application and how you intent to use it.
Basically if the application needs any of the features provided by a Unix FS
and which are not available in FAT (better use VFAT at least), then you are
lost.
Examples:
- hardlinks (usually bash and sh are two links to the same binary)
- softlinks (often used for configuration files)
- named pipes (often used for IPC; although most times they will be created
in /tmp)
- sockets (same)
- device or character special files (rarely created or used by a program
directly)
- if the program uses any kind of user/group permissions to control access
If you really must install the program on a FAT partition, then you may want
to look at UMSDOS. UMSDOS emulates a UNIX filesystem on top of FAT.

Subject: ide cdrom :lost interrupt
Date: Thu, 18 Feb 1999 01:22:11 GMT
I have a PII-333 w/ 64MB RAM. I am running a new install of RedHat 5.2 with
Mandrake and kernel 2.2.x additions. I am trying to get my IDE-ATAPI 32x
CDROM running under kernel 2.2.x. Currently, whenever I try to mount it I
get:
'hdb: lost interrupt'
and it hangs the machine with the reset button being the only way out. I
have tried moving (and jumpering) it from the master of IDE-2 to the slave of
IDE-1. But there was no change. I tried scsi-ide emulation with no success.
If I don't have a CD in the drive it merely fails to mount. If I do, it
spins up the CD and leaves it spinning indefinately after it is hung.
My SCSI Ricoh CD-RW works just fine, I can mount and umount it with impunity.
I have tried 2.2.0 and 2.2.1 from www.kernel.org and 2.2.1 from the RawHide
distribution.
If anyone has a suggestion, I would like to hear it.
Thanks,
Joe Dennis

Subject: Re: NFS Data Corruption between Linux 2.2.0pre4 and SunOs 5.5.1
This looks like a Solaris bug.
bug id 4071076 data over length in nfs header was written to disk
It is fixed in Solaris 7.
It appears to be patched in Solaris 2.5, 2.5.1, and 2.6, and
according to access1.sun.com, the 5 of the 6 release/architecture
combinations of patches are free.
http://access1.sun.com/search.html
and search for
4071076
However, that search doesn't seem to produce the Solaris 2.5.1 sparc patch.
The x86 2.5.1 patch is 105300-02, and the README file says that
sparc patch is 105299. 105299-02 is the level that has the fix for
2.5.1 sparc. As far as I can tell, this patch isn't free.
What I'm puzzled by is that
ftp://sunsolve1.Sun.COM/pub/patches/Solaris2.5.1.PatchReport
doesn't list 105299-02 as being available to even customers with
maintainence contracts. Engineering finished
105299-02 a year ago. I'm checking around.

What are your mount options? I didn't see any NFS related problems
since mounting with "actimeo=0". (This doesn't mean there are no more
problems. Besides using this mount option I don't do any critical work on
NFS-mounted partition anymore - I lost an important file with one of the
2.1.12x kernels).

Hi all.
In Linux when we read a large file, it may be used indirect pointer to
access data.
If a block is already caching in buffer cache.
Is the block also accessed by indirect pointer?

Subject: .name undocumented?
I found in /usr/src/linux/Makefile that one can create a .name file, the
contents of which will be used as a suffix on the new kernel version. Is
this documented anywhere? This looks like a way to build a new
/lib/modules/xxx directory that doesn't overwrite the working one.
For example, if one creates a /usr/src/linux/.name containing the word
"experimental", then "make modules_install" should put the modules in
/lib/modules/2.0.36-experimental.
This is in the RH5.2 distribution. RH also supports a .rhkvmtag file in
the modules directory which is used in rc.sysinit to determine which
modules directory applies to the current kernel. Again, I could find
nothing documenting this feature.
Also, what does /boot/module-info do? This and /boot/System.map are set
up at boot time by the same rc.sysinit code, but I haven't found mention
of module-info in the docs for the module utilities.

Ok, I think I'm understanding my problem. I thought
it only had to do with configuring the kernel CD driver,
but now I think it has to do with the kernel sound

I have a Sound Blaster 16. It is xmixer that acts different

You probably also want to make sure that your BIOS supports bootable
CD-ROMs. AFAIK, most older ones (and even some newer ones) don't. If you
aren't sure, check your motherboard documentation or the manufacturer's
website. Alternately, you can check the BIOS type and version at startup
and check the BIOS manufacturer's website for version info.
I remember reading a webpage that had detailed instructions on how to do
make an iso image in RockRidge (Joliet [win9x's filesystem] handles
fileneames and permissions differently) format while in Windows or Linux;
it's definitely less complicated in Linux (uses "dd"). But I can't seem to
find it again. :( It's also possible to find an iso image of the CD on the
web (I used Mandrake's distrobution mirrored at
ftp://canine.resnet.gatech.edu/pub/linux-mandrake/). It does take quite
awhile to download 580 MB (180 min at 550kb/sec avg.), but much less
complicated or prone to error.
G'luck!

Subject: OpenGL for Linux and problems with kernel compatibility (AudioPCI people,

Date: 19 Feb 1999 01:01:28 GMT
Here's what's up: I've been trying to explore the possiblities of
installing OpenGL for my 3Dfx card on my machine but encountered several
difficulties: Unfortunately, it's not compatible with my kernel: I've had to
run v2.2.1 so that I can have the drivers for my sound card (An audioPCI
card). But, it seems that pci specifications for the new kernel have been
changed. That presents problems with 3Dfx which relies on certain pci calls. I
tried changing the code but still had problems. So here's what I'm wondering:
Will 3Dfx ever be included as part of the Linux kernel? Everybody pretty much
has a 3D card these days and it would open new graphic possibilities up to
Linux. Also, how can I somehow get a more stable kernel running.. say 2.0.36
but also get the AudioPCI (I've searched for the drivers but with no luck). I
figure that's the only way I'll get OpenGL up and running on my system...
Would be nice if the next kernel release was a little more
comprehensive..
