Description of problem:
Using the patch boot.img disk to solve the known issue with the controler.
I type linux apic. The system loads its startup files then the screen goes
blank and locks. only way to get it to respond is do a cold boot.
System is an Intel ISP2150 no addin cards. 1 processor 6-mhz p3.
terminator in 2nd slot. 64 mb ram 2 segate sca scsi drives and a ide cd-
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.boot from patch disk
2.type linux apic
Actual Results: system hang with no video
Expected Results: continuance of install
I was getting kernal panic:tryed to kill init! before. Did a couple
changes in the bios(install os :changed to pnp, pci2031 bridge option now
enabled, pci irq's to IO-APIC Mapping now disabled)
this got me out of the kernel panic situation but thats about it.
I've seen lots of other post about the l440gx+ boards here but none with
the specific problem with the video.
Does the anaconda installer even start or does it hang during the kernel boot?
it hangs on the kernel boot. What I think is occuring is that the kernel is
finishing loading ok(not sure because I'm new to this. but when it tries to go
to anaconda I lose video(although I lose video before it has a chance to
say "starting anaconda"
Since it seems that the kernel isn't even fully booting, I'm going to change the
component to the kernel.
"changed to pnp" -> please change that back
also can you try "apic ide=nodma" as options ?
ok now I'm getting the kernel panic again. I can't post a screen shot but I
will type it out.
top part scrolls off screen but here is whats left. hopefully this will shead
