installing redhat8 on ibm345 via pxe

[K.C. Chan]

All,
I am installing redhat 8 on an ibm box which has the Broadcome NetXtreme Gigabit NIC. I am able to install it via pxe for redhat9; however I am unable to the same for redhat 8. Here's the entry in default under /tftpboot/pxelinux.cfg:

label blade-rh8
kernel vmlinuz-rh8
append load_ramdisk=1 initrd=initrd-rh8.img network ksdevice=eth0 ks=nfs:10.10.10.33:/redhat/kickstart/blade.cfg

I don't think there is anything wrong with this entry. Since it is able to boot with it but failed on kickstart, got an error of can't find kickstart in /tmp/ks.cfg. I've check to make sure that bcm5700 and tg3 is listed in initrd. If both driver is in initrd, why can't it get an ip address via dhcp? Here's what is in the log file:
in.tftpd[19258]: tftp: client does not accept options

Hi K.C.

The most likely cause if this issue is either a lack of driver support on Red Hat 8 or a possible bug in the driver that ships with Red Hat 8.

Red Hat 9 is a better way to go unless you have a specific reason to use Red Hat 8.

Steven,
I need to be able to use Redhat 8, there may be an issue with Redhat 9. Thanks for the input.
