The IDE part works very well, though there seems to be some problems with userland tools (mke2fs), an instruction is probably not/bad emulated. I now have a system with the root on the IDE drive and with swap. The initrd seems to works well, but it generates a strange failure during the boot: [...] Mount-cache hash table entries: 512 Checking for 'wait' instruction... available. checking if image is initramfs...it isn't (bad gzip magic numbers); looks like an initrd Bad page state in process 'swapper' page:81010000 flags:0x00080000 mapping:00000000 mapcount:0 count:0 Trying to fix it up, but a reboot is needed Backtrace: Call Trace: [<8005c748>] bad_page+0x68/0xa8 [<8005ccf0>] free_hot_cold_page+0x1a4/0x1b4 [<802a0000>] ic_bootp_recv+0x238/0x6a0 [<80080138>] __fput+0x14c/0x1cc [<8001b094>] free_init_pages+0xa4/0xfc [<802a0000>] ic_bootp_recv+0x238/0x6a0 [<802a0000>] ic_bootp_recv+0x238/0x6a0 [<802a0000>] ic_bootp_recv+0x238/0x6a0 [<80288d98>] free_initrd+0x28/0x44 [<80288e80>] populate_rootfs+0xcc/0x110 [<80292860>] spawn_softlockup_task+0x30/0x50 [<80010498>] init+0x54/0x300 [<80010498>] init+0x54/0x300 [<80013074>] kernel_thread_helper+0x10/0x18 [<80013064>] kernel_thread_helper+0x0/0x18 Freeing initrd memory: 2520k freed NET: Registered protocol family 16 NET: Registered protocol family 2 [...] This message is not present when initrd is not used, and it also does not appear with the previous way of passing the size and location of the initrd.
