RE: ADLO for EPIA

I mean I did as Slumicki suggested. First I booted with original EPIA bios. Then changed image with linuxbios and did soft-reset while power is on. This can be done because I have rom-emulator. > -----Original Message----- > From: Andrew Ip [mailto:aip@cwlinux.com] > Sent: Wednesday, March 12, 2003 1:22 PM > To: hcyun(a)etri.re.kr > Cc: adam(a)cfar.umd.edu; linuxbios(a)clustermatic.org > Subject: Re: ADLO for EPIA > > > > I tried but no success. > In the current cvs tree, vga is not enabled.

Both keyboard and mouse are plugged and of cause I can boot linux with LinuxBIOS. Is there any board depedent part other than shadow memory control? For now, I just want to see screen output from VGABIOS or BOCHS BIOS.

I tested ADLO on EPIA but it failed on the first try. I grapped vgabios using your Makefile target and modified loader.s to enable shadow ram control registers of EPIA. However, it hang around post code 0x96 and nothing is shown on the CRT. Do you have any idea what 0x96 post code means. Is it a bochs post code or vgabios postcode? > -----Original Message----- > From: Adam Sulmicki [mailto:adam@cfar.umd.edu] > Sent: Tuesday, March 11, 2003 4:13 AM > To: hcyun(a)etri.re.kr > Cc: linuxbios(a)clustermatic.org > Subject: Re: ADLO for EPIA > > > > I'm trying to bring up VGA on EPIA board. > > >From the list, EPIA board is supported and I've tested > with Angrew's image. > > However, due to full support of VGA is necessary, I'm > trying to figure out > > ADLO to run binary only > > VGABIOS rom image. > > Can I acomplish this with ADLO?.

ADLO for EPIA
by hcyun＠etri.re.kr 10 Mar '03

10 Mar '03

Hello, I'm trying to bring up VGA on EPIA board. >From the list, EPIA board is supported and I've tested with Angrew's image. However, due to full support of VGA is necessary, I'm trying to figure out ADLO to run binary only VGABIOS rom image. Can I acomplish this with ADLO?. If yes, how much extra work will be needed you think? Thanks, - HeeChul Yun, Embedded S/W Team at ETRI phone: +82-42-860-1673

Because the IPL area in doc2000 can't be rewrited, DiskOnChip 2000 16M doesn't support linuxbios. You may use Doc Milliennium 16M. ========================== 263电子邮件－信赖邮自专业
