Has anyone yet tried PXE booting the vmlinuz/initrd.img set from Centos 4.0beta2? I have a pxelinux setup that is booting 3.4 PXE images fine, but the equivalent setup for 4.0beta loads the kernel and then splashes the monitor full of multicolor random characters. Not a good start to an install... Anyone had luck? Any changes for PXE boots known for 4.0? Thanks in advance. -Alan

This causes horkage when the video card is not well suported.> Anyone had luck?

I tried to pass args to the kernel ( vga= .... nofb ; etc ). I also did some tcpdumps and noticed he loads vmlinuz fine, fully. then he doesn''t try to load initrd, because of the crash. 2.4 pxe kernels provided with the CD1 of centos 3.3,3.4, 3.1 works fine ... I guess the problem is an issue because this is a 2.6 kernel .... in other hand, the original centos-4 CD1 is booting fine on all system i''ve tested. I''m very suprised to see i''m alone with Alan to have this problem ... I don''t know what to do more :P

Using the same platform I used for CentOS 3 (worked great). PXElinux 3.07 for bootloader. Have tried about every boot option available as well (nousb, noapic, nomce, apic, nopcmcia) to no avail.

I''ve tested on three differents hardware : a PowerEdge 1850, and two differents i386 PC, it results in the same flashing chars issue, just after "..............." with *no* "Loading vmlinuz.." to begin. -- Martin

I can see no obvious sign that vmlinuz is actually starting, more like a blob of bad code just started and toasted the boot. Double-checked the vmlinux and initrd I''m using, they are not corrupted... -Alan

The posted kernel seems to work for most people, and it only doesn''t work for a very few. I built a new kernel / initrd.img for PXE that is i686 only (not the default i586 kernel), for people who are specfically having problems. You can get that PXE kernel / initrd.img here: http://centos.hughesjr.com/testing/i686_pxeboot/ -- Johnny Hughes <http://www.HughesJR.com/>
