Hi, I checked the pentium manuals, could not find any reference to these statements as listed below. > > andl $0x7FFAFFD1, %eax /* PG,AM,WP,NE,TS,EM,MP = 0 */ > > orl $0x60000001, %eax /* CD, NW, PE = 1 */ The syntax for and is reverse and <register> <immediate value> Whereas the code reads andl <immediate value> <register> Could someone please help me on this or redirect to exact reference for the above statements. Regards Deepak > you really need to get a pengium manual. Where do I get this one. Is it some Linux Man Page. Could you please give me the link where I can look for it.

RE: serial debug patch for ADLO
by hcyun＠etri.re.kr 22 Apr '03

22 Apr '03

The patch doesn't initialize serial port because it assume serial was already initialized by linuxbios. I think your problem is you didn't enabled debugs flags. you must enable DEBUG_ROMBIOS and also appropriate debug flags you want to see such as DEBUG_INT15, DEBUG_INT16 and etc. Heechul > -----Original Message----- > From: klos [mailto:klos1980@sina.com] > Sent: Tuesday, April 22, 2003 4:45 PM > To: hcyun(a)etri.re.kr; adam(a)cfar.umd.edu; linuxbios(a)clustermatic.org > Subject: RE: serial debug patch for ADLO > > > Hi, > It seems to have no responds in my serial port; I use > etherboot to load the ADLO. > Loading 192.168.1.1: payload > ... > (ELF)......................................................... > ...................... > ................done > No more information. > > Some one gives me some suggestions? > > Baud rate? > > > Best regards > klos > -----Original Message----- > From: linuxbios-admin(a)clustermatic.org > [mailto:linuxbios-admin@clustermatic.org] On Behalf Of > hcyun(a)etri.re.kr > Sent: 2003年4月19日 23:07 > To: adam(a)cfar.umd.edu; linuxbios(a)clustermatic.org > Subject: serial debug patch for ADLO > > Hello, > I made a patch which make all bochs debug message can be seen > from serial terminal. > I think it might be useful if you want to apply ADLO to your > own target. > you can apply this patch againt util/ADLO/bochs/bios/rombios.c by > # patch -p0 < rombios-serial.patch > Regards, > > >

Is reset32.inc required ?
by Shubhangi Jadhav 22 Apr '03

22 Apr '03

Hi, I'm trying to port Linuxbios to a motherboard which has a VIA C3 processor. For this I'm using l440bx mainboard config file as a reference. In the config file I found reference to the following includes : cpu/i386/entry16.inc cpu/i386/entry32.inc cpu/i386/reset16.inc However there's no reference to reset32.inc. Is it required to add reset32.inc, please let me know. Regards, Shubhangi

About 82810e north bridge
by Deepak Kotian 22 Apr '03

22 Apr '03

Hi, There seems to be two devices in Intel 82810e north bridge, one is Memory controller Hub and other is Graphical controller HUB. Is it OK to just do the initialization for Memory controller HUB and forget about Graphical controller HUB. Also, I saw 82815ep on linuxbios tree, which has support for MCH only and no AGP. This is very much similar to 82810e with some address changed. What would happen if I support MCH for 82810e , will LinuxBIOS still come up. Could someone please give an opinon on this. Thanks and Regards Deepak
