Description of problem:
After creating an installation floppy with boot.img the systems stops booting
after "uncompressing linux ... ok booting the kernel". I can boot the machine
with kernls up to 2.4.19-pre6 if I pass a mem=512M parameter at boot time.
Kernels from 2.4.19-pre7 onwards don't boot.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. creating an installation disk (from RH 7.3 or beta "NULL")
2. booting machine
Actual Results: system hangs completely after showing "uncompressing linux ...
ok booting the kernel"
Expected Results: system boots; starting installation
Pentium 4 (1.6 GHz Northwood)
i845E chipset (Chaintech board)
512 MByte DDR RAM
it seems that this problem is BIOS related. memtest86 is reporting only 640kByte
of memory via the e820 procedure. Adding "mem=exactmap mem=640k@0 mem=511M@1M"
as boot parameter solves the problem - other problems like initialising ehci-usb
controler and ide come up
