Hi mates, I have 3 PCs at home: 1) The older one (10 years): MB Elpina MVP3 + S, PC100 AGP Pro, 9827 BA/E-VO, Rev.3.0, Socket Super 7, AMD K6-2 550 Mhz. 384 Mb. RAM (its full supported configuration) 2) The medium age one (4 years): MB Asus A7V-E, AMD Athlon Thunderbird 1.4 Ghz., 1024 Mb. RAM (its full supported configuration) 3) The newest one (2 months): MB Biostar K8M80-M2, AMD Athlon 64X2 4,200+, 1024 Mb. Ram. As you may see I was always hocked with AMD. Referring to the Elpina mobo it doesn’t recognize a 40 Gb. HD, but I still not sure if it is the same as the PCChips M577 or Amptron 9900, so I'm afraid to flash its bios with 990309J2.BIN. And reading the Jan’s document it causes me more doubts due he says that 990309J2 patch must be made over the 990306s and even I don’t know if this is the bios the Elpina actually has. Even I don’t know if the eprom chip itself could be flashed. It reads: Award PCI/PNP 586 S/N 11501609 1997 And has a sticker over it which reads: BURNS-IN 24HR The actual (it has never been upgraded) full Elpina bios info that I got running BiosAgent.exe from Unicore.com is: String: 07/15/1998-577 + ITE8661-2A5LEH0AC-00 Release: 07/11/1998 S Date: 07/15/98 Type: Award Modular Bios v4.51PG Award Plug n Play Bios extension v1.0A Chipset: VIA 82C597 rev 4 Super IO: ITE 8661/SiS 6801 rev 2 found at port 0279h Sending above info to Unicore.com (they seems to be the official Award bios upgrade seller) they say that have a new bios at 29.95 Bucks!!!! but I don’t know if it’s newest than 990309J2. So I need your support helping me to clear up all these doubts.
