Still something wrong. I try boot from BOOT-PROM disk 3 and:
- first run PC - boot OK - reset PC - boot hangs - other reset - boot hangs but in other moment - other reset - boot hangs
Booting from Floppy... Floppy_drive_recal 0 Floppy_enable_controller Floppy_media_sense on drive 0 found rate 0 Booting from 0000:7c00 Floppy_disable_controller Floppy_enable_controller Floppy_drive_recal 0 Floppy_media_sense on drive 0 found rate 0 i8042_command cmd=ae i8042_wait_write i8042_command cmd=ae i8042_wait_write floppy error: 40 04 00 1c 00 05 02 invalid basic_access:96: a=00000200 b=00000000 c=00001c05 d=00000000 ds=5000 es=6080 ss=df80 si=00000000 di=00005750 bp=0000001e sp=0000f9c0 cs=5000 ip=0188 f=0246
but this is only from this disk. Other read OK.
BOOT-PROM1 - ok BOOT-PROM2 - ok BOOT-PROM3 - bad but other PC with vendor bios read this floppy OK gPXE 1.0.1 (PCI) - ok gPXE 5.4.4 (ISA) - ok RIS (RGFG) - ok PLOP 5.0.11 - ok netboot.me - ok
P.S. SeaBIOS make exclamation in WinXP on device manager on Realtek RTL8139 NIC :-(
