Mikael Pettersson 1514ab09ed [x86 setup] APM detection logic bug fix ... Starting with kernel 2.6.23-rc1, the i386 APM driver fails on several of my machines with the message: apm: BIOS not found This happens because of a bug in the i386 boot code rewrite from assembler to C. The original assembly code had the following code in its APM BIOS presence test (boot/setup.S): andw $0x02, %cx # Is 32 bit supported? je done_apm_bios # No 32-bit, no (good) APM BIOS That is, the code bails out if bit 2 is zero. In the new C version, this is coded as (boot/apm.c): if (cx & 0x02) /* 32 bits supported? */ return -1; Here we see that the test has been accidentally inverted. The fix is to negate the test. I've verified that this allows the APM driver to work again on my affected machines. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: H.
