I know that if I have IDE HDD, I can use hdparm -d 1 /dev/hda to
increase the speed of my HDD, but is it relate to scsi HDD?

Subject: How to connect to my Palm?
I have install mandrake with the tools that
support palm. After I start gnome and follow the
instruction to sync palm and linux, my palm report
can't connect to system.
Where can I find more information?
I connect my palm with serial com1, should I use ttyS0?

Subject: Adsl-start as start-up script
I would like to connect to internet upon the system start, so I try to
connect to internet at console using adsl-start, but it can't work. Can
anybody tell me how to set it?
I can successful connect to internet at gnome using mandrake tool but
can't connect at console using adsl-start. Actually I can get the IP and
start the ppp0 adapter, but I can't ping to internet.

dude- there is only one sane thing to do when somebody has gotten access
to your root-password who shouldn't have:
take the machine of the net.
wipe it.
re-install from scratch
secure it
*maybe* *think* about putting it back on the net
How the hell do you know they don't have access anymore? Once somebody
has gotten root, they could set up all kinds of trojans that let them get
back in no matter how often you choose your password.

Subject: How Linux calc memory?
After I start Linux, I check the memory usage with gtk gtop, and it
report my tomcat use 330 MB memory and mozilla use same amount, it just
impossible because I only have 128 MB memory and aboout 250MB swap. Why
will I get these figure?

No. When power is applied to the SCSI device and its bus, the device
and the card negotiate to find out the highest speed both are capable of
handling, and they use that speed. You can speed up your SCSI devices
by:
buying a better SCSI card (PCI > ISA)
upgrading the SCSI bus (Ultra > Wide > Narrow)
buying faster SCSI devices (10000 RPM > 7200 RPM)
hacking the SCSI drivers in an intelligent way (good luck!)

I went to that home page but I don't know what does it mean with create

how can a create those directories.

Type: stty erase <backspace-key>
Typically Unix boxes use ^? and Windows boxes use ^h, but it doesn't
matter if type the above with whatever key you want for backspace.
What is a mystery to me is that when I use an xterm (or gnome terminal or
Konsole) RedHat and Mandrake automatically use what they need when
connecting to each other, and BSDi automatically recognizes each, but
Solaris ISP does not. When I log into Solaris with RedHat it works fine,
when I login with Mandrake, I have to do the stty erase ^? thing.
My ISP originally set up their login to default to ^h, but I modified it
so if TERM=linux, it would set TERM=vt100 and use ^? for erase. But I
don't know how to recognize when I am using RH xterm or Mandrake xterm.

no. your scsi hard drive has nothing to do with dma.
your scsi host adapter aka scsi controller will usually be a
busmastering card and can thus transfer directly into memory.

Acrobat will display landscape documents fine. A landscape document
has, of course, the long side of the PAGE in the X direction. The
authors of some software are confused about this. Rather than change
the page dimensions, they use a portrait page and rotate the
contents. This works fine with printers, where you can turn the page
after it comes out. It doesn't work well on the screen.
If you are stuck with a package that insists on a page size 8.5x11
with "portrait" and "landscape" buttons, try a user-defined page size
of 11x8.5. That's what landscape really means. Change the page
dimensions, not the orientation.

A problem with X or the font server, maybe? You could look on SmartBeak
to see if anyone else has had the problem, or ask on the Applix mailing

]Type: stty erase <backspace-key>
It is a mess. The key <- on the top right of the keyboard can be set up
to send either ^H or ^? and each program which grabs the ekyboard can do
different things with it. Thus in Mandrake, you can tell the OS to set
up <- to send ^H. But then in KDE, on the terminal screen, it will send
^H to the terminal but ^? on a remote connection.
As I ranted on on another thread, it is all the fault of Dec and its VT
terminals and Vax computers, and then emacs grabbing ^H for its own
purposes, so we now have a total mess.
stty only tells the terminal what to do with the charactes it gets, it
does nothing about what character the key actually sends to the system.

Probably because you have all of your systems set up to use ^? as the
backspace, and that is what that key sends.
