Description of problem:
I am tring to install RedHat 9 on PC. I boot the PC from CD. I selected a
graphical install. The kernel starts to load and gets to the part /sbin/loader
and then the screen blanks. I am not totally sure if the command
is /sbin/loader because the monitor goes blank as soon as it flashes on the
screen. I then tried linux text at the boot prompt, same problem. Then I
tried linux lowres, same problem. I have a tyan tiger 100 S1832DL motherbaoard
with 256MB of RAM. I have an adaptec 2930U2 SCSI card with two 9GB hard
drives, ID 0 and ID 1. 1 Plextor SCSI CD-ROM (ID 3). 1 3Com 905B ethernet
card, 1 Actiontec internal PCI call waiting modem (a real modem, not a
winmodem). I have a Number nine Revolution IV video card with a SGI 1600SW
monitor. The install looks like it would continue because I pressed enter a
few times and the CD and HD started to spin up, but I can't see anything on the
Version-Release number of selected component (if applicable):
anaconda-whatever is on the cd
Steps to Reproduce:
1. Boot a redhat 9 disk 1
2. Select any option
3. The kernel text scrolls by, the text or graphical part starts but nothing
displays on the monitor.
Actual Results: The screen is blank. The light on the monitor is flashing
like it lost the signal from the video card.
Expected Results: I should be able to see something
Try adding 'skipddc' to the command line.
I tried linux skipddc and it didn't work. I forgot to mention the native
resolutions for this monitor are 800x512 and 1600x1200. Do you have any other
I am sorry I made a typo eariler. The native resolutions are 800x512 and
1600x1024 not 1600x1200.
Try 'linux nofb text'.
Using linux nofb text I was able to install redhat 9. My sgi 1600sw showed up
as an unknown monitor. Can you please add support for the sgi 1600sw monitor?
I will forward this issue report to the X configuration group.
Does it show up if you run 'ddcprobe'? Do you have an INF file?
