No need for this. LILO can be set to boot winders by default. Just add
default=DOS (or winders, or whatever) to lilo.conf. Change the /dev/hda*
values as needed for your situation.

boot=/dev/hda

With a huge buffer size (4 megs), and a block size of 32768 bytes, I was able
to write:
4,018,284,544 bytes
= 3832.13 Mbytes (1MB =1024^2)
= 3.7423 GBytes (1GB =1024^3).
I am trying with a smaller block size and without buffer to see what happens.

Hi. Thanks to chem engr I got X running OK, by using CyberBlade.
However, 15 bit color is just not going to work, so I am moving on.
I did a startx -- -bpp 15
The result was that xdpyinfo showed 15 planes and 15 bits, but
it was obvious that colors were wrong, and gcolorsel showed obvious problems,
meaning that despite the server running 15 planes, the hardware was doing
16 planes (5 red, 6 green, 5 blue). So that's the end of that fiasco.
Thanks to everyone for their help anyway I learned a lot.

Hi,
I'm trying to install Redhat 6.2 (kernel 2.2.14) on a Dell Dimension
with a 40 Gig IDE Hard disk. The installation cannot proceed beyond the
partition drives stage, as Redhat simply does not detect the hard disk
Does anyone know how to overcome this problem? I did see a note on the
Redhat site that I should get kernel 2.3.21 and install it, though i
don't know exactly how i could do it, unless i already had installed
Linux on the system
thanks,
-unmil.

Here's a bit of an update:
I looked into RedHat bug #10418 and downloaded the latest aic7xxx driver
(5.1.31) from Doug Ledfords web page
(http://people.redhat.com/dledford/aic7xxx.html). This did not change
anything, I still get exactly the same behavior.

Hi.
I have DVD-RAM/PD drive (LF-100) and its performance, especially
writing performance, become very bad in linux-2.2.16.
Up to 2.2.15, scsi.c was responsible for the DVD-RAM driving. I found
this is changed in 2.2.16. In 2.2.15, I could make partitions to the
DVD-RAM,
the read/write performance was not very bad. At lease I could do other
jobs while copying to DVD-RAM. But in 2.2.16, fdisk says that I have to
set heads sectors and cylinders manually, which I do not know, and
when writing a 600MB class file to PD, the foreground job can be quite
a lot disturbed by the copying.
Please let me know how can I help to solve this problem. Thanks.

HI!!!
Please help me (again). I've a ISDN-Telephon, wich runs on other PC but not
on mine. The kernel supports ISDN, but although I send the right AT
commmands I dont get a answer of the telephon. But it works perfectly on
windoze :( !!!
Could it be that linux doesnt open the COM1 (ttyS0) port correctly, so that
the phone doesnt get any commands? How can I open this port on C/C++? How
can I check out if the ttyS0 works or not?
Thanks

Hi Guys,
My old P133 is getting a bit tired now and I wan't to build myself a
shiny new one based around 2x700Mhz Pentium III's and a SCSI disk.
I've been looking at the motherboards suitable (very hard to find info
on dual boards isn't it ?) and it seems that the Asus P2B-D is quite a
popular choice BUT it's looking a little dated now and I was wondering
if there are any better (ie 133 FSB) boards for the above setup ? (not
too worried about overclocking - stability, features and at least 1xISA
slot are my main priorities)
Two more little questions:
1) Is onboard SCSI a good thing or is more trouble than it's worth ?
2) Can FCPGA chips operate in SMP or should I stick to Slot 1 and the BX
chipset ?
Rgds,
Ian.

I don't know what /dev/zip points to, what does "ls -l /dev/zip" return?
(it should show a link to the actual /dev entry for the zip partition: e.g.
/dev/sda4)

the "noauto" option in the fstab entry specifies NOT to auto-mount at boot
time!
and the "user" option allows regular (non-root) users to (un)mount it.

The ppa stuff installs the zip drive as a SCSI device, generaly /dev/sda
and the DOS partition is number 4
so to mount it by hand you could try typing:
mount -t vfat /dev/sda4 /mnt/zip
and see if that works!
hope this helps! - bluster

What kine of IDE controller are you using? If you are using the Promise
Ultra66 then you should either pull it out and use the onboard ATA33
controller, or you will have to recompile the kernel.

OK, I tried doing the cdrecord binary is now SUID root, and I've made sure that
the sg module is loaded (and confirmed using lsmod). I'm still having no luck

I've now compiled version 1.8.1 of cdrecord and replaced the one installed by
default on the system. As I previously stated, "cdrecord -scanbus" still doesn't
work. However, now when I try:
cdrecord -v speed=4 dev=0,6,0 <CD IMG>
I now get:

We are trying to add 2 SCSI drives onto our system. This system comes with
2 builtin controllers (SCSI1, SCSI2). We added an additional SCSI
controller (SCSI0), for our tape backup unit.
We also, have an external SCSI drive unit with two 9GB drives that will only
attach to SCSI0. The problem is that when we power up the external SCSI
drive unit, and reboot the system, The drives are nolonger in their correct
order. These drives are now assiged as sda and sdb. All of the other
drives now move up 2 letters.
Is there anyway that we can stop linux from reassigning the devices?
What needs to be done to the server so that it will boot from sdc(old sda)?
Thanks
