From e50cbe8eb763cf63fb44b047d5164f6fbf07eb39 Mon Sep 17 00:00:00 2001 From: Alejandro Sior Date: Fri, 13 May 2022 20:50:39 +0200 Subject: boot: longmode to realmode stub This is the initial commit to the repo. It adds all the code. The last proper thing that I got working before committing is calling real mode functions from long mode using a stub. Next up, I would like to implement a disk reader abstraction over the BIOS in order to read form partitions (most notably FAT32). --- .bochsrc | 58 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 .bochsrc (limited to '.bochsrc') diff --git a/.bochsrc b/.bochsrc new file mode 100644 index 0000000..394d356 --- /dev/null +++ b/.bochsrc @@ -0,0 +1,58 @@ +# configuration file generated by Bochs +plugin_ctrl: unmapped=true, biosdev=true, speaker=true, extfpuirq=true, parallel=true, serial=true, iodebug=true +display_library: wx, options=gui_debug +#display_library: options=cmdmode +memory: host=32, guest=32 +romimage: file="/usr/local/share/bochs/BIOS-bochs-latest", address=0x00000000, options=none +vgaromimage: file="/usr/local/share/bochs/VGABIOS-lgpl-latest" +boot: floppy +floppy_bootsig_check: disabled=0 +floppya: type=1_44, 1_44="/home/aws/rep/boot/boot.bin", status=inserted, write_protected=0 +# no floppyb +ata0: enabled=true, ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14 +ata0-master: type=none +ata0-slave: type=none +ata1: enabled=true, ioaddr1=0x170, ioaddr2=0x370, irq=15 +ata1-master: type=none +ata1-slave: type=none +ata2: enabled=false +ata3: enabled=false +optromimage1: file=none +optromimage2: file=none +optromimage3: file=none +optromimage4: file=none +optramimage1: file=none +optramimage2: file=none +optramimage3: file=none +optramimage4: file=none +pci: enabled=1, chipset=i440fx, slot1=none, slot2=none, slot3=none, slot4=none, slot5=none +vga: extension=vbe, update_freq=5, realtime=1, ddc=builtin +cpu: count=1, ips=4000000, model=bx_generic, reset_on_triple_fault=1, cpuid_limit_winnt=0, ignore_bad_msrs=1, mwait_is_nop=0 +#cpuid: level=6, stepping=3, model=3, family=6, vendor_string="GenuineIntel", brand_string=" Intel(R) Pentium(R) 4 CPU " +#cpuid: mmx=true, apic=xapic, simd=sse2, sse4a=false, misaligned_sse=false, sep=true +#cpuid: movbe=false, adx=false, aes=false, sha=false, xsave=false, xsaveopt=false, x86_64=true +#cpuid: 1g_pages=false, pcid=false, fsgsbase=false, smep=false, smap=false, mwait=true +#cpuid: vmx=1 +print_timestamps: enabled=0 +debugger_log: - +magic_break: enabled=1 +port_e9_hack: enabled=0 +private_colormap: enabled=0 +clock: sync=none, time0=local, rtc_sync=0 +# no cmosimage +log: - +logprefix: %t%e%d +debug: action=ignore +info: action=report +error: action=report +panic: action=ask +keyboard: type=mf, serial_delay=250, paste_delay=100000, user_shortcut=none +mouse: type=ps2, enabled=false, toggle=ctrl+mbutton +#sound: waveoutdrv=win, waveout=none, waveindrv=win, wavein=none, midioutdrv=win, midiout=none +speaker: enabled=true, mode=sound, volume=15 +parport1: enabled=true, file=none +parport2: enabled=false +com1: enabled=true, mode=null +com2: enabled=false +com3: enabled=false +com4: enabled=false -- cgit v1.2.3
