Hi! A few days ago, my friend bought a laptop machine whose APM BIOS is version 1.1. But APM BIOS driver of 2.0.5-ALPHA says that the version of APM BIOS is 53.14(?). On this case, apm_init routines finds that the version of APM BIOS is 0101 (OK!), but I think apm_driver_version() crashes this value. When APM_DEBUG is defined, it says: Jun 6 21:40:25 lavender kernel.APM_TEST: apm0 on isa Jun 6 21:40:25 lavender kernel.APM_TEST: found APM BIOS version 0101 Jun 6 21:40:25 lavender kernel.APM_TEST: apm0: Code32 0xf00f0000, Code16 0xf00f0000, Data 0xf00f0000 Jun 6 21:40:25 lavender kernel.APM_TEST: apm0: Code entry 0x0000b37e, Idling CPU disabled, Management disabled Jun 6 21:40:25 lavender kernel.APM_TEST: apm0: CS_limit=1f, DS_limit=ab2d Jun 6 21:40:25 lavender kernel.APM_TEST: [5300 504d 001b 0 53] Jun 6 21:40:25 lavender kernel.APM_TEST: [5300 504d 001b 0 53] Jun 6 21:40:25 lavender kernel.APM_TEST: apm0: Engaged control disabled Jun 6 21:40:26 lavender kernel.APM_TEST: found APM BIOS version 53.14 Jun 6 21:40:26 lavender kernel.APM_TEST: apm0: Idling CPU disabled Jun 6 21:40:26 lavender kernel.APM_TEST: Warning: APM engage function failed [1] -- HOSOKAWA, Tatsumi E-mail: hosokawa@mt.cs.keio.ac.jp WWW homepage: http://www.mt.cs.keio.ac.jp/person/hosokawa.html Department of Computer Science, Keio University, Yokohama, Japan
