I noticed other errors while boot without any floppy inserted to FDD and i new SeaBIOS new other errors :-( - without floppy in FDD something wrong Timeout errors - in WinXP in device manager exclamation in RTL8139 - debug errors with INT10 - debug errors with PCI RTL ROM please look at log, this is boot PC without any floppy inserted to FDD (coreboot have floppy0 and pci rom added): =~=~=~=~=~=~=~=~=~=~=~= PuTTY log 2013.12.12 10:29:52 =~=~=~=~=~=~=~=~=~=~=~= coreboot-4.0-4772-ga4affe1-dirty Thu Dec 12 10:49:49 CET 2013 starting...

Next release (2.0) will have seabios 1.7.4 (or newer) which will actually read the acpi tables from qemu, a snapshot is in git master already. switching over smbios is at discussion stage right now, nobody has written any patches yet and as far I know nobody is actively working on it. cheers, Gerd

[PATCH 3/3] floppy: Implement cylinder seeking when accessing a different cylinder.
by Kevin O'Connor 12 Dec '13

12 Dec '13

It appears that on real hardware, floppies require a seek command to move the floppy head between cylinders. So, track what cylinder is active and issue a seek command whenever a new cylinder is requested. This also breaks up the floppy_cmd() code so that the low-level command functions can pass the desired cylinder directly to the seeking code.

[PATCH 1/3] floppy: Encode command and flags into single value in floppy pio code.
by Kevin O'Connor 12 Dec '13

12 Dec '13

Eliminate struct floppy_pio_s and change floppy_pio() to take the command type and parameters in a single encoded value. This makes the code similar to the ps2port.c pio code. It also reduces some of the boilerplate code in the callers of floppy_pio().

Re: [SeaBIOS] [coreboot] Patch number 4 for floppy in SeaBIOS

First patch is applied OK, i tested one more time. Second patch is more better. FDD now read more data from floppy :-). Read very slow probably because debug is ON. After end is more, more, more null <00> I break serial log Ctrl+C. PC not boot to end and stop booting while: ========================= A:\keyb pl,,keyboard4.sys ========================= but I remembered about this: http://www.coreboot.org/pipermail/coreboot/2013-November/076643.html and try boot from other floppy and successfully boot :-) :-) :-)
