It has been shown that the synchronous updating of metadata is the wrong
|
|
thing to do. You may have a system which shows no fsck errors after a
|
|
crash, but has garbage in the newly created files anyway.
|
|
I'd rather lose a new file alltogether than have it in the directory and
|
|
have crap in it instead of the data I wrote.
|
|

|

|

Of course there is development in Linux, and FFS is old. So the picture
|
|
may well change over time. But I have not had ext2 corruption problems
|
|
ever since I started using it, so I can't comment on e2fsck.

|

|
|
|
|
It is easy to configure it so that it will fsck very often. But when that
|
|
is required you probably have some hardware problem. Or maybe you shutdown
|
|
your system by simply cutting the power while it is expiring the news??
|

|
|
|
|
You can enable "slower but safer synchronous inode and directory updates"
|
|
for ext2fs as well, but as mentioned before it is not safer at all.

I'm using a Zeos P90 PCI - it has only been a few days since I installed,
|
|
though. Seems like it runs just fine and smaller load on heavy tasks than
|
|
I get on NETCOM at 3:30 am ;) I haven't got X to run yet; xinit complains
|
|
about a missing config file. My configuration is:
|
|
|
|
Zeos P90, 16 MB RAM, 540 MB IDE HD & 340 MB IDE HD, Mitsumi CD-ROM (*),
|
|
2 * 16550 serial ports, Phoenix BIOS (v4.0??), Diamond Stealth 64 (using
|
|
the S3 Vision 964 64-bit chip - not tested yet...), Practical Peripherals
|
|
PM14400FXMT modem - not tested yet), Microsoft mouse (not tested yet).
|
|
|
|
I been throught a lot of the standard Unix utils, and they all seem to run
|
|
just fine.
|
|
|
|
(*) The Mitsumi drive, as configured by Zeos, needs the command "mcd=0x310,10"
|
|
when booting the Mitsumi kernel otherwise Linux won't recognize the drive.

Just thought I'd second that. I've taken a look at wxWindows and

subscribed to the mailing list. It seems a very active mailing

list. Julian Smart that started wxWindows seems to be very active

For someone that wants to start some GUI programming without

There is allready a driver for the Teles/S0 card which was written for linux
|
|
BUT it uses a port of the NetBSD-Networking code so it should be less trouble
|
|
to port than one might think. It currently supports the german TR6 standard
|
|
but it shouldn't be to difficult to add support for Euro-ISDN and the US
|
|
standard. Any way it's a start and it might be worth looking into.

I am using a toshiba 1910 with a megahertz pcmcia modem. I downloaded the

set of drivers (pcmcia-2.2), upgraded my kernel to 1.1.49, and installed the
|
|
new module utilites.
|
|

When I start the machine, the card manager is started. It finds the modem,

and creates the symbolic link to /dev/modem. However, if i try to access it,
|

through seyon, minicom, or using echo atd > /dev/modem, all I hear are clicks

from the speaker. I can get any response from the modem (no OK, no ERROR). If

anyone has any better luck or clues, I would appreciate it.

I made a backup of my dos partition using the command 'tar cM *', and
|
|
it worked fine and prompted me for the 3 volumes needed. Then
|
|
when I was restoring (after reformatting the dos partition and changing
|

the partition type to primary bootable instead of extended) I used
|
|
the command 'tar xM'. it worked until it propmted me for the second volume,

and then it reported (after I put the second volume in and hit return)
|
|
'this is not volume 2, insert volume 2' (paraphrased).
|
|
|
|
It refused to continue the multivolume tar no matter what I did.
|
|
Fortunatly, when I did a 'tar x' on the second volume it restored
|
|
all files except for the first file which was continued from volume 1.
|
|
I only lost the file that spanned vol 1&2 and the file spanning 2&3,

all the rest of the files I got back ( using tar x instead of tar xM)
