The kernel is 2.4.13, the initrd is around 64M. The netbooted client is a 1.5G memory HP Vectra 420. It can successfully netbooted with 512M memory. But can not boot when memory is added to 1024M and 1.5G. The error prompt is something like: Kernel panic: VFS: Unable to mount root fs on 01:00 I'm using Official kernel 2.4.13, the base system is RedHat 7.1 on HP vectra 420. The commands I used to create the tagged images is: /usr/bin/mknbi-linux --output=./kernel.test.0540 --ip=dhcp --rdbase=0x5b000000 --rootdir=/dev/ram0 --append="idebus=66 ide0=ata66 ide1=ata66 ro" bzImage initrd I also tried options, --rdbase=top/asis/0x00300000, all can failed with the same above problem. At last I use local hard disk boot, with the same kernel (4G high memory option enabled), it can boot successfully, then I tried to see the memory mapping, and get the following information: arc251.alexa.com guolin 64% cat /proc/iomem 00000000-0009fbff : System RAM 0009fc00-0009ffff : reserved 000a0000-000bffff : Video RAM area 000c0000-000c7fff : Video ROM 000c8800-000c9fff : Extension ROM 000ca000-000cdfff : reserved 000e0000-000effff : Extension ROM 000f0000-000fffff : System ROM 00100000-5ffeffff : System RAM 00100000-002794af : Kernel code 002794b0-002efd17 : Kernel data 5fff0000-5fff7fff : ACPI Tables 5fff8000-5fffffff : ACPI Non-volatile Storage d7a00000-dfafffff : PCI Bus #01 d8000000-dbffffff : PCI device 1002:5446 (ATI Technologies Inc) dfb00000-dfbfffff : PCI Bus #02 dfd00000-dfdfffff : PCI Bus #01 dfdfc000-dfdfffff : PCI device 1002:5446 (ATI Technologies Inc) dfe00000-dfefffff : PCI Bus #02 dfeff000-dfefffff : Intel Corporation 82820 (ICH2) Chipset Ethernet Controller dfeff000-dfefffff : eepro100 e0000000-e3ffffff : Intel Corporation 82845 845 (Brookdale) Chipset Host Bridge fff00000-ffffffff : reserved Please suggest which method, I can try to netboot the machine.

It depends on what you are doing. With mnknbi --rdbase. With other bootloaders it varies. The easy solution is to get a newer kernel.
