Dimitri, The same initrd works when I boot over TFTP using pxelinux.0, but it doesn't work from the web directory, so I think the initrd is good. Thanks for archlinux link.
Andrew, I tried loading the initrd first before the kernel, i.e. gPXE> dhcp net0 DHCP (net0 mac-address).... ok gPXE> initrd http://ip-addres/gpxe/initrd............................................................................................................. ..................................................................................................................................................... ..................................................................................................................................................... .......................(20 lines of this) is the result for about ten minutes now. Same problem. The initrd IS a huge file at 143MB, but my network downloads that size file over tftp in about a minute. gPXE was loading the 1.4 MB vmlinuz file in one second, so it seems gPXE knows how to download a file quickly. Can the initrd command take parameters like a bigger blocksize, say 4096?
