.SH EXIT STATUS
flashrom exits with 0 on success, 1 on most failures but with 2 if /dev/mem
(/dev/xsvc on Solaris) can not be opened and with 3 if a call to mmap() fails.
.SH REQUIREMENTS
flashrom needs different access permissions for different programmers.
.sp
.B internal
needs raw memory access, PCI configuration space access, raw I/O port
access (x86) and MSR access (x86).
.sp
.B it87spi
needs raw I/O port access (x86).
.sp
.BR nic3com ", " nicrealtek ", " nicsmc1211 " and " nicnatsemi "

.sp
.B atahpt
needs PCI configuration space access and raw I/O port access.
.sp
.BR gfxnvidia " and " drkaiser
need PCI configuration space access and raw memory access.
.sp
.B satasii
needs PCI configuration space read access and raw memory access.
.sp
.B serprog
needs TCP access to the network or userspace access to a serial port.
.sp
.B buspirate_spi
needs userspace access to a serial port.
.sp
.BR dediprog " and " ft2232_spi
need access to the USB device via libusb.
.sp
.B dummy
needs no access permissions at all.

.sp
.BR serprog ", " buspirate_spi ", " dediprog " and " ft2232_spi
can be run as normal user on most operating systems if appropriate device
permissions are set.
.sp
On OpenBSD, you can obtain raw access permission by setting
securelevel=-1 in /etc/rc.securelevel and rebooting, or rebooting into single
user mode.
