Hp pavilion ze43000 notebook and hp f4809a battery

The HP Pavilion ze4300 (hp f4098a battery ) is a rather inexpensive typical desktop notebook. It has some nice features, among which the one-touch buttons and builtin CD-RW/DVD-R and floppy drives. Another nice thing is the screen, which supports a resolution of 1400x1050, and the touchpad with integrated "scroll-mousewheel" (Synaptics touchpad). As one of increasingly few notebooks it still has a RS232 serial adapter (which for me was one of the main arguments, often having to deal with "headless" devices). It is (apart from the ACPI stuff, which works only partially) fully supported by Linux and very handy and comfortable to work with.

Before purchasing

HP has a politics of using different components for each and every country that they sell hardware to. So the configuration of the machine is likely to widely differ from that of a model purchased in another region. . Having made some rather tiresome experiences, I took a swiss-germanized version of Knoppix 3.2 with me, booted it and controlled if everything worked. It did. hp f4098a battery here

Base installation

In the meantime, I'm running Gentoo with a quite different software set. I've tried to insert Gentoo specific stuff into this document as necessary.) The installer detected almost all hardware components and initialized the necessary modules (see original modules.conf for SuSE and for Gentoo. The only thing that was missing, was the onboard modem chip, and the CD-writer wouldn't work. Sound was OK, network OK, graphics flaky (X came up with errors, and the maximum resolution wasn't reached). Obviously, none of the one-touch buttons would work. Now, having relaxed while watching the YaST installer (which I usually don't use), it was time to go to work. ( The above goes for SuSE only. Gentoo, too, didn't see the modem chip, but the CD writer worked with the same options. X is quite different, because Gentoo doesn't install X per default, and when I decided it's time for some eye candy, I went for X.org's X Window system. In the meantime, Xfree86 is fading into history.) The onetouch Buttons ("Mail" and "WWW", as well as the volume control keys) strangely worked, though. This was probably due to the acme package in Gnome, after deinstalling it, the volume control stopped working, but not the "Mail" and "WWW" buttons.)

Graphics

After playing awhile with SuSE's X-configuration tool SaX2, I decided for the easy way. Remembering that Knoppix had used the whole resolution range, I again booted into Knoppix and just copied over the interesting parts of the /etc/X11/XF86Config-4 file. While SuSE's SaX2 insisted that I use the framebuffer device driver fbdev (probably because of the AGP host bridge, which seems not to be recognised), Knoppix suggested the VESA driver, which brought up X in high resolution (1400x1050) without errors (see XF86Config-4) and a working scrollmouse. Well, that was the easy way, wasn't it?

Onboard modem

Traditionally, this scares you away, since onboard modems usually are socalled "Winmodems", i.e. modems that are too stupid to do anything and rely on the operating system do deal with the gory details of handshaking, handling protocol stacks, communication etc. Times have changed, though. lspci revealed an "ALi Corporation Intel 537 [M5457 AC-Link Modem]" chip, and after Google and .. brought me to the (although ethically questionable) resolution of using a non-free driver from .I used version 5.03beta, which works well and doesn't have a speed limitation. Unfortunately, linuxant has since changed their policy, so that the "free" (as in free beer ¦-[ ) driver is limited to 14.4Kbps data, while you have to pay for the 56K and fax driver. And, unfortunately again, they have put a paragraph in their license that prevents me from making the package available to you here. But then, who still needs modems, right?
