Linux - Howto

General installation for notebooks with SIS630 / SIS630S / SIS630ST chipset
Installation of a new Linux kernel for notebooks with SIS630 / SIS630S / SIS630ST chipset
Installation of X-Window with a native driver ( i.e. without the framebuffer device ), for notebooks with SIS630 / SIS630S / SIS630ST chipset
Installation of X-Window and the framebuffer device, for notebooks with SIS630 / SIS630S / SIS630ST chipset

In the past, computers with SIS630 / SIS630S / SIS630ST chipset must setup the framebuffer device to make X-Window run ! Read the SUSE 7.1 manual, chapter 8, "The X Window System", subchapter 8.3.3, "Troubleshooting - The graphics card is not supported" and check the "SUSE Support knowledgebase" for the keyword FRAMEBUFFER, but follow the instructions provided here.

The Clevo 2700c BIOS offers the menu option "Startup / Display" to activate display devices:

In fact, with either setting, both LCD and CRT display devices are activated: If you connect a VGA monitor to the notebook and if the VESA BIOS is active, there is always a display on the VGA monitor. Both devices are always addressed in 1024x768 resolution, so that the display quality of the display resolutions 640x480 and 800x600 is reduced the same for LCD and CRT.
Graphics screen resolution VESA video mode Effective monitor screen width Horizontal sync frequency Vertical sync frequency
textmode - 1024x768 49 KHz 60 Hz, non-interlaced
648x480 vga=785 1024x768 49 KHz 60 Hz, non-interlaced
800x600 vga=788 1024x768 49 KHz 60.5 Hz, non-interlaced
1024x768 vga=791 1024x768 49 KHz 60 Hz, non-interlaced
So while a Linux text console is displayed, or if X-Window uses the VESA framebuffer driver, the VESA BIOS is active and controls the horizontal and vertical sync frequencies. Just if a X-Window server is running, using a special SIS 630S driver and while the X-Window console is displayed, the horizontal and vertical sync frequencies are taken from the file "/etc/X11/XF86Config" !

So be aware, VGA monitors with a maximum horizontal frequency of less than 49 KHz, as usual in the early 1990th, don't work with this notebook !

In opposite to MSDOS and Linux, Win98SE and W2K always override the VESA BIOS by its special graphics drivers.

Linux network installation tips

In addition to the built-in network adapter, my notebook is equipped with an NE2000 compatible "10M Ethernet COMBO FL-4680" PC Card of Fiberline Technology Corp., distributed in Germany by Seditec and sold by Atelco and Pearl Agency. I found a confirmation of inofficial Linux support for this PC Card.
